Optical processes in semiconductors will give you improved knowledge and skills in optoelectronics and related industrials through the understanding of fundamental characteristics of optoelectronic devices. The subject is recognized as an important one to accomplish sustainable developments of society. Final goal is to learn optical absorption and emission processes in semiconductors so as to understand spectroscopic data and to get advanced skills.

Fundamental solid state physics for under graduate students, in which crystal structures, reciprocal space, phonon, and band structure for semiconductors are included.
