Content, Learning Outcome and Preconditions
This module will introduce the students to the physics of semiconductor-based electronic and optical devices, their functional characteristics, and their physical realization. The following devices and structures will be addressed in detail:
Semiconductor contacts: Ohmic and Schottky metal-semiconductor contacts, metal-insulator-semiconductor (MIS) contacts, and semiconductor-semiconductor contacts
Diodes: Schottky diodes, basic p-n junctions, tunnel diodes, avalanche diodes, and Gunn diodes
Bipolar transistors and thyristors
Field effect transistors (FETs), in particular metal-oxide-semiconductor FETs (MOSFETs)
Optoelectronics: light-emitting diodes (LEDs), semiconductor lasers, photodetectors, and solar cells
Selected elements of microelectronics: CMOS logic, dynamic random access memory (DRAM), and charge-coupled devices (CCDs)
After successful completion of this course the students possess a basic knowledge of devices discussed, including their physical foundations, functional characteristics (e.g. current-voltage characteristics), and applications. This will provide them necessary knowledge to understand the components of modern semiconductor electronic and optoelectronic devices. Students are also able to
- Draw and explain energetics of various semiconductor junctions
- Explain the physical basis for current-voltage characteristics of different semiconductor electronic devices
- Explain the physical structure, typical operating ranges, and limitations of devices
- Explain how the different devices are used in technological applications

Learning and Teaching Methods
The method of instruction is through lectures, in which questions and discussion are encouraged. Fundamental concepts are further illustrated with modern technological examples.
Description of exams and course work
There will be a written exam of 90 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
- • Derive the current-voltage characteristics of a Schottky diode.
- • Explain the functional principle of a bipolar transistor. What is the benefit of using a heterobipolar transistor?
- • Sketch the idealized drain characteristics of a MOSFET and discuss the physics of the different regions of the MOSFET behavior.
- • Draw the band diagram of a diffusion solar cell. How is recombination reduced at the two different surfaces?
The exam may be repeated at the end of the semester.
