COURSE OBJECTIVES
THE AIM OF THE LECTURE IS TO PRESENT A BASIC KNOWLEDGE ABOUT BASIC PHYSICAL
PROPERTIES OF SEMICONDUCTORS STARTING FROM FOUNDATIONS OF
CRYSTALLOGRAPHY, BONDING IN CRYSTALS, X-RAY DIFFRACTION, FOUNDATIONS OF
QUANTUM STATISTICS OF CHARGE CARRIERS AND THEORY OF TRANSPORT PHENOMENA
WHICH ARE THE BACGROUND FOR SEMICONDUCTOR ELECTRONICS AND
MICROELECTRONICS. ADDITIONALY, AN UDERGRADUATE STUDENT GAINS KNOWLEDGE ON
BASIC PROPERTIES OF TWO-DIMENSIONAL ELECTRON GAS AND LOW-DIMENSIONAL
STRUCTURES BEING THE BASIS FOR NANOELECTRONICS. BASED ON THE DISCUSSED TOPICS,
A STUDENT SHOULD DEVELOP ABILITY TO UNDERSTAND INTUITIVELY THE DISCUSSED
PHYSICAL PHENOMENA AND TO USE A CORRECT PHYSICAL TERMINOLOGY.
PREREQUISITES
KNOWLEDGE ABOUT FUNDAMENTALS OF PHYSICS
(KINEMATICS, ELECTROMAGNETISM, OPTICS, STRUCTURE OF
ATOMS), MATHEMATICAL ANALYSIS (DIFFERENTATIONS,
INTEGRATIONS), AND QUANTUM MECHANICS (TIME
INDEPENDENT SCHRODINGER’S EQUATION).
KNOWLEDGE:
