Entry knowledge

The student who enrols in the course should be able to use the Cartesian coordinate system, should operate to solve simple cases of uniform motion and uniformly accelerated motion, Newton's laws and the laws of conservation of energy and momentum. He should be able to describe the basic structure of matter at the atomic level, further to explain the term of the electric charge, the electric current. He should be able to use the basic quantities describing the electric and magnetic fields and to assess the impact of these fields on the movement of electric charge. He should be able to describe the oscillating mechanical harmonic motion and to explain the mechanical progressive wave. He should be able to apply the basic laws of geometrical optics (the laws of reflection and refraction) for solving rays of light propagation. Students should be familiar with the mathematical apparatus at the level of basic work with vectors, differentiation and integration of scalar and vector functions of a scalar argument.
Generally, the knowledge on the technical university bachelor degree level is required.

Rules for evaluation and completion of the course

Students can obtain up to:
- 25 points from the semester project (solving of given problems or elaboration of a given topic)
- 20 points from laboratories (6 reports),
- 55 points from the exam (a written part of 35 points and a verbal part of 20 points).
Students must obtain at least 10 points in the written part to proceed to the verbal part.
Students must obtain at least 5 points in the verbal part to pass the exam.
The exam is focused on the verification of basic knowledge in the field of electrical and optical properties of solids, including solving of selected problems.
Laboratory exercises are compulsory, properly excused missed labs can be compensate after consultation with the teacher.

Aims

The objective is to provide students with knowledge of selected electrical and optical properties of solids, including examples of a wide range of interesting applications. Practical knowledge will be verified in the laboratory exercises.
The student is able to:
- explain the behavior of an electron in a potential well and a potential barrier,
- describe the basic nanostructures and their applications (quantum wells, wires, dots, a single light emitting diode, a single photon detector),
- describe the basic properties of atoms,
- describe the crystal structure of solids and explain the formation of energy bands,
- describe the drift and diffusion in solids,
- compute the mobility of charge carriers from the experimental data,
- compute the lifetime of minority carriers and the diffusion length of minority carriers from the experimental data,
- apply the continuity equation and Poisson's equation,
- describe the basic types of generation and recombination processes in semiconductors,
- describe the formation and properties of a PN junction,
- describe a LED and a solar cell.
