Minority carrier lifetime in GaP grown by liquid phase epitaxy for high temperature applications
Journal Article

· J. Appl. Phys.; (United States)
We have measured the minority carrier lifetime tau/sub min/ in liquid phase epitaxial GaP material grown for high-temperature device applications, as a function of doping concentration, temperature, and epitaxial layer thickness. In p-type GaP doped with Mg, tau/sub min/ remains constant with increasing carrier concentration until proughly-equal10/sup 18/ cm/sup -3/, where it decreases rapidly. For nominally undoped n-type material we find that tau/sub min/ increases by nearly one order of magnitude over the temperature range T = 22--600 /sup 0/C. The apparent lifetimes in these thin-layer materials increase with layer thickness indicating that surface and interface recombination are important.
