The Burstein-Moss Shift in Quantum Confined Infrared Materials

  • Kamakeya P. Ghatak (a1) and Badal De (a2)

Abstract

In this paper we have investigated the Burstein-Moss shift in quantum wires and dots of III-V and II-VI materials on the basis of Kane and Hopfield models for the appropriate carrier dispersion laws. It is found taking Hg1−xCdxTe, In1−xGax AsyP1−y lattice matched to InP and CdS as examples that the Burstein-Moss shift exhibits oscillatory dependences for quantum wires and dots of the said materials with respect to doping and film thickness respectively. Besides, the numerical value of the same shift is greatest in quantum dots and least in quantum wires. In addition, the theoretical analysis is in agreement with the experimental datas as given elsewhere.
