Magnetoluminescence studies in ordered InGaP{sub 2}

PDF Version Also Available for Download.

Description

Photouminescence measurements on ordered InGap{sub 2} were studied as a function of temperature, laser power density, and magnetic field. The temperature varied between 1.4 and 300 K, the laser power densities ranged from 10 nW/cm{sup 2} to 20 W/cm{sup 2}, and the maximum magnetic field was 13.6 T. The data show both excitonic and band-to-band behavior, depending upon the incident laser power density. A consistent interpretation of all data leads to a type-II valence-band offset between the ordered domains. Finally, a charge transfer model between domains which provides an explanation for intensity dependent energy shifts is discussed.
