Lecture

The lecture covers physics and technology of modern compound semiconductors with major focus on III-V compounds like GaAs and related materials. These semiconductors are indispensable for modern optoelectronic devices like LEDs (all visible colors, infrared, ultraviolet), laser diodes, photodetectors, etc., where silicon is useless due to its indirect band structure. Moreover, they find applications as high-frequency electronic devices in modern communication systems like mobile phones, etc. In the lecture, we will discuss the physics which enables these applications, the preparation of the materials, epitaxial structures and devices and some particular characterisation methods.
