Prel. scheduled hours: 36
Rec. self-study hours: 124

  Area of Education: Science

Subject area: Physics
  Advancement level (G1, G2, A): A

Aim:
The objective of the course is to transfer a basic understanding for fundamental properties and characteristics for semiconductors, but also how these properties can be utilized for various applications within the electronics. In addition within the frames of the course, a description of the most important methods to fabricate semiconductor materials together with introducing doping in the material will be provided. He course aims at an improved understanding of the effect caused by a reduction of the dimensionality of a semiconductor; from the 3-dimensional bulk, via 2- and 1-dimensional quantum wells and -wires, to 0-dimensional quantum dots.

Knowledge and understanding: After the course, the student should

  • understand and describe in own words the optical, electrical and transport related properties of the semiconductors
  • describe different types of doping and the effect of doping for various properties in the semiconductors
  • understand and describe in own words the effect of a reduced dimensionality in a semiconductor
  • describe different lattice types and energy band models, which are applicable on semiconductors

Aplications and evaluation: After the course, the student should

  • be able to calculate parameters like the charge carrier concentration, Fermi-energy, doping levels and â?"energies together with the mobility as evaluated from experimental results
  • demonstrate an ability to independently select and employ adequate computational methods in order to determine the doping energies for bulk as well as quantization effects in semiconductor quantum structures
  • be able to use some common electrical and optical characterization methods on semiconductors

Ability to communication: After the course, the student should

  • be able to write a laboration report with an analysis of experimental results and error sources together with an estimate of error levels
  • be able to find and utilize adequate and relevant information from a simpler scientific article and be able to give an oral presentation of this information
