About
the course
The course provides comprehensive understanding
of compound semiconductors, stressing how differences from Silicon enable
unique applications in electronics, photonics, photovoltaics,
and thermoelectrics. The compound semiconductor
materials discussed include those from the semiconductor families of group IV (SiGe, SiC), III-V (GaAs, InP, GaN),
II-VI (ZnO, CdTe), and
layered semiconductors (MoS2, Bi2Se3, BN, etc), and will touch on organic and dilute magnetic
semiconductors. Methods of crystal growth, doping, strain control, and
fabrication will be discussed. Electronic bandstructure
will be used to develop band diagrams of complex heterostructures
and nanostructures including quantum wells, wires, and dots. Examples of
these semiconductor materials in electronic, photonic, thermoelectric, and
solar cell applications will be used to motivate the materials science.
