TFFY35 Semiconductor Physics, 5 ECTS-points
/Halvledarfysik/

Advancement level:
D

Aim:
The development within electronics is currently very rapid and new devices are continuously introduced. The prerequisite for this rapid development is the improvement of the semiconductor material. This course if of fundamental character and basic physical properties of the semiconductor material are presented. The properties of three-dimensional (3D) bulk material constitutes a major part of the course, but also recent developments within low-dimensional semiconductor structures, such as heterostructures, superlattices and quantum wells, are an essential part of this course. Also various modern techniques for growing and doping of semiconductor materials are presented. Furthermore, different ways to electrically and optically charaterize semiconductors will be demonstrated at the three laborations, which are included in this course.

Prerequisites:
TFFY 70 Material Physics, TFFY 54 Quantum Mechanics is recommended.

Supplementary courses:
TFFY 34 Semiconductor Technology, TFFY 96 Solid State Electronics
