Abstract
A detailed characterization of undoped and Be doped Low temperature grown InGaAs-InAlAs structures is undertaken to correlate the structural point defect behavior with obtained electrical and optical properties. By a judicious combination of doping and annealing temperatures, materials with sub-picoseconds lifetimes and resistivity of ~ 1×107 ohm/square have been obtained. This is the highest resistivity reported to date for this material system.
