Nanyang Technological University, Singapore
Title:
Electronic structure and optical properties of dilute nitride bismide semiconductors
Abstract:
In this talk, we will review our recent work on the electronic structure and optical properties of GaAsNBi semiconductor quantum wells and quantum dots. The calculation is based on the 16-band k.p method. Band anti-crossing (BAC) and valence band BAC will be applied to 8-band k.p Hamiltonian to form the 16-band k.p method. Strain effect is taken into consideration in the model. The band structure and optical gain spectra will calculated and discussed.
