  • Abstract
    A photoconductivity study has been made of nominally undoped VPE n-InP materials grown on semi-insulating InP:Fe substrates. The photoresponse spectra obtained indicate features characteristic of Cr deep acceptors. By comparing the magnitudes of the photoresponse with that of a back-doped InP:Cr reference sample, the concentration has been estimated at between 2 and 8×1014 cm¿3.
