Abstract

The ionization energies of C, Be, and Mg acceptors in InP have been determined by means of low-temperature (1. 7-20 K) photoluminescence measurements on high purity epitaxial and bulk samples which have been implanted with low (5 multiplied by 10**9 minus 5 multiplied by 10**1**1 cm** minus **2) doses of those impurities. The measured values are 44. 6 plus or minus 0. 3, 41. 3 plus or minus 0. 3, and 41. 0 plus or minus 0. 3 mev, respectively. A comparison with the ionization energies of the residual acceptors in liquid phase epitaxial (LPE), PH//3-vapor phase epitaxial, liquid encapsulated Czochralski, and polycrystalline samples indicates that C is almost never present as a residual acceptor in undoped InP. The ionization energy of the main residual acceptor in the LPE samples matches that of both Mg and Be.
