Synopsis:

The aim of this course is to provide postgraduate students with a deeper and more detailed insight into principles of and properties of advanced electronic and optoelectronic structures. Completion of this course enables doctoral students to deepen the basic knowledge, which they obtained in the bachelor and master stages of study in the field of semiconductor structures and elements. They will be able to solve scientific tasks in electronics and optoelectronics focused on design, analysis and applications advanced electronic and optoelectronic structures. The student will gain deep knowledge of physics principles of PiN and MOS structures, as these dominate the current integrated and power semiconductor technology. The lecture will be further focused on the use of new principles associated with miniaturization and the use of advanced materials. Higher-order phenomena whose knowledge is essential for understanding the current semiconductor devices will be described. It is expected that the course will focus on specific issues according to the interests and scientific focus of the participants.
