Optical properties of semiconductor quantum wires
… presents theoretical investigations of the subband structure and optical properties of semiconductor quantum wires. For the subband structure, we employ multiband effective-mass theory and the effective bond-orbital model both of which fully account for the band mixing and material …

Electronic and optical properties of semiconductor quantum wells
… quantum wells. The light and heavy hole subbands are strongly hybridized and this subband mixing has important effects on electronic and optical properties. A systematic study of the mixing effects on valence subband structure, exciton binding energies and oscillator strengths, and …

Optical properties of confined and unconfined excitons in semiconductor quantum heterostructures
… excitons in semiconductor quantum heterostructures are investigated. We use multiband effective mass theory to solve the subband structure in which valence band mixing is properly taking into account. With the aid of supercomputer and recently developed k-space sampling technique we can …

MULTICOLOR INFRARED DETECTION USING STEP QUANTUM WELLS
… infrared photodetectors (QWIPs) based on intersubband transitions are widely investigated in recent years. Due to the mature III-V material and processing technology, great progress has been made successfully for the fabrication of large scale quantum well infrared focal plane arrays (FPA). In …
