Abstract

For the first time, a novel passivation method for 1.7 eV bandgap polycrystalline GaInP is discussed theoretically and demonstrated experimentally. Post-growth deposition of aluminum and annealing treatment is used to passivate the GaInP thin-films. The proposed passivation technique is predicted to form a type-I heterostructure at the surface and at the grain boundaries. Dependence of the photoluminescence spectrum of polycrystalline GaInP alloys on annealing temperature and time is reported. A 210-fold increase of photoluminescence peak intensity after post-anneal treatment suggests significant recombination reduction of surface and grain boundaries.
