Landolt-Börnstein - Group III Condensed Matter

4.2.4 Other well materials


This chapter describes some less commonly investigated well material combinations. Various material combinations are listed concerning their band alignment and their growth. The chapter shows the band alignment in a bilayer quantum well structure with the envelope functions of the first quantized electron and hole states. A review of linear optical properties including excitonic effects, band to band and intersubband transitions and Raman scattering is provided. Linear optical spectra at low electron-hole pair densities including excitons and interband transitions as well as intersubband transitions is plotted. Photoluminescence and absorption spectra of InAs/AlSb MQW structure at 5K are given. The chapter presents the data of optical nonlinearities in the low and medium-density regimes, investigations of characteristic time constants and applications of the nonlinearities in optical modulators and switches. The influence of external fields (strain, electric, magnetic) and of built-in strain fields has been investigated. In order to study the plasma effect, data are compiled which are relevant for uni- or bipolar carrier plasma.
