- Use the relationship between the fundamentals of the theory and the different electronic properties of the network and observed experimentally.
- Understand the influence of the dimensionality of the system on these properties.
TOPIC 1 classical and quantum free electron models: the model of Drude and Sommerfeld model. Effect of the periodic potential of the network in the properties of the electron gas.
In this first issue approximations are introduced for the electrical, thermal conductivity and the Hall effect in a gas of free electrons. Sommerfeld model: Here the effect of the quantization of energy and the Pauli exclusion principle on the electronic and statistical properties of the model of free electrons is described. The specific heat, and electrical conductivity. The drawbacks of the free electron model and the need to take into account the interaction of electrons with the periodic potential of the lattice to describe real systems are described.
Then Brillouin zones are explained, the Bloch theorem and band theory is formulated to free electrons. Density of electronic states.
Finally it is shown as the appearance of energy gaps in the bands of forbidden electronic states are a consequence of the interaction with the periodic potential.
TOPIC 2 quantization energy network. Phonons
This topic energy quantization network is explained and the dispersion relation for a monatomic one-dimensional network in the harmonic oscillator approximation (speed of sound and thermal conductivity) is calculated.
Optical and acoustic modes: the effect of breaking the symmetry (two different atoms, more than one dimension, etc) on the dispersion relation is introduced.
Debye model for the thermal conductivity and thermal expansion is introduced.
TOPIC 3. Experimental in determining electrical properties and thermal transport techniques.
Fundamental aspects of the main experimental techniques will be explained in the determination of properties of electrical and thermal transport in solids: electrical conductivity, thermal conductivity, thermoelectric power and Hall effect.

The lectures will be given on blackboard with PowerPoint support.
Seminar sessions and tutorials will be held to resolve specific problems
This methodology will be adapted to the various scenarios provided by the USC:
SCENARIO 1. Adapted normality (without restrictions to physical attendance)
A) Expository classes: The teacher will present in class those aspects of the lesson that he considers essential for the understanding and development of the activities that will be proposed. During the expository sessions the teacher will use PowerPoint slides that serve as a script to follow the schedule. Usually these classes will follow the contents of a proposed Reference Manual.
B) Interactive classes - Seminars: Theoretical / practical class in which applications of the theory, problems, exercises are proposed and solved ... The student is expected to actively participate in these classes in different ways: preparation of group work, delivery of exercises to the teacher (some of those proposed in problem bulletins that the teacher delivers to the students in good time); solving exercises in the classroom, etc.
SCENARIO 2. Distance (with partial restrictions on physical attendance)
The way of distributing teaching between expository and interactive sessions is maintained, the only thing that is modified is the way in which these sessions will be carried out and the type of interaction between teachers and students.
The lectures will be done online and the tools of the USC will be used: Virtual Classroom (Moodle) and MS Teams.
The seminars will be carried out combining 50% the face-to-face and telematic sessions. For the latter, the Virtual Classroom and MS Teams will be used. In face-to-face sessions, the minimum safety distance will be maintained. They will be shorter sessions to allow the rotation of the subgroups if necessary.
The tutorials will be telematic and the Virtual Classroom and MS Teams will be used.
SCENARIO 3. Closure of facilities (impossibility of teaching face-to-face)
The lectures will be done online and the tools of the USC will be used: Virtual Classroom (Moodle) and MS Teams.
The seminars will be conducted telematically using the Virtual Classroom and MS Teams. The tasks completed during these sessions that must be corrected will be delivered through the Virtual Classroom.
The tutorials will be telematic and the Virtual Classroom and MS Teams will be used.
SCENARIO 1. Adapted normality (without restrictions to physical attendance)
The evaluation will be made attending to two aspects:
• Continuous evaluation: 40% (Activities proposed by the teacher in seminars and tutorials, controls and evaluation tests, etc.)
• Final exam: 60%
The continuous evaluation grade will only be obtained through "active" participation in the activities that make up said evaluation (class presentations, class problem solving, ...), in order to demonstrate that the knowledge set for each of the such activities.
The final exam will include theoretical questions and problems related to the subject included in the subject's program, regardless of whether the subject was worked in the expository, interactive or practical classes. The exam will be graded on a total of 10 points.
In cases of fraudulent performance of exercises or tests, the provisions of the Regulations for evaluating student academic performance and reviewing grades will apply.
SCENARIO 2. Distance (with partial restrictions on physical attendance)
The evaluation system does not undergo any modification with respect to what has already been indicated in the section corresponding to scenario 1. The same percentages of continuous evaluation and exam are maintained to obtain the final grade for the course.
The “active” participation in the activities that make up the continuous evaluation will depend on the attendance to the face-to-face sessions, the involvement and participation during the telematic sessions and the deliveries made through the virtual Classroom.
The final exam of the subject will be done electronically using the Virtual Classroom Questionnaires tool combined with simultaneous session in MS Teams. The contents that will be evaluated in the exam will be the same as those indicated for scenario 1.
SCENARIO 3. Closure of facilities (impossibility of teaching face-to-face)
The evaluation system does not undergo any modification with respect to what has already been indicated in the section corresponding to scenario 1. The same percentages of continuous evaluation and exam are maintained to obtain the final grade for the course.
The “active” participation in the activities that make up the continuous evaluation will depend on the involvement and participation during the telematic sessions and the deliveries made through the virtual Classroom.
The final exam of the subject will be done electronically using the Virtual Classroom Questionnaires tool combined with simultaneous session in MS Teams. The contents that will be evaluated in the exam will be the same as those indicated for scenario 1
The student, personal work is divided into 36 hours of personal study and 18 hours of related work directed and supervised by the teacher activities.
• It is very important to attend all classes.
• Problem solving and self-assessment exercises is key to learning this subject. It may be helpful to start with the fixes in handbooks and reference, to follow after the problems given at the end of each chapter in the Reference Manual.
• It is essential to consult the literature and try to complete advanced aspects with the most fundamental concepts that are explained in the class.
Contingency plan
Scenario 1: Adapted normality (without restrictions on physical presence).
The development of this subject will be fundamentally face-to-face, although in an exceptional and justified way, telematic teaching can be combined with face-to-face teaching up to a maximum of 10% of the hours of the subject, and in the case of practical teaching carried out with telematic means, the 25%.
Tutorials can be partially carried out electronically.
In scenario 2, two modalities are contemplated: 100% physical presence, when the teaching organization allows it; and a combination of 50% physical presence and 50% telematics.
The tutorials will preferably be done electronically.
Scenario 3: closure of the facilities (impossibility of teaching face-to-face teaching).
The development of the will be completely telematic in nature, with synchronous or asynchronous mechanisms.
The tutorials will be exclusively telematic.
