Field effect transistors: basic principle, MOSFET, heterostructure FET, Tunnel diode, single electron transistor, Coulomb blockade.

6. Optoelectronic devices based on quantum heterostructures Optics of quantum structures, light emitting diodes and lasers

Books:

Basic Semiconductor Physics by Chihiro Hamaguchi

Lectures:

Lectures are usually based on his detailed slides but often he dives into details for which blackboard is then used but otherwise it is all slides. He usually doesn’t have an attendance policy for his courses

Assignments:

Each of us were tasked with making a presentation on the extra topics and also make a Latex document of it as well. They were challenging and very interesting mathematical results. This took some time.

Exams and Grading:

There were no exams or quizzes in this course when i took it

Online Useful Material:

Pro-Tips:

Enjoy the classes. The professor cares that you learn new things and enjoy the classes than assessing you. Doesn't mean it is easy.
