Title: | Surface recombination velocity in GaAs and In0.15Ga0.85As thin films | Authors: | BRAMMERTZ, Guy Heyns, Marc MEURIS, Marc Caymax, Matty Jiang, Dehuai Mols, Yves Degroote, Stefan Leys, Maarten Borghs, Gustaaf |
Issue Date: | 2007 | Publisher: | AMER INST PHYSICS | Source: | Applied physics letters, 90 (13) (Art N° 134102) | Abstract: | The authors have made photoluminescence intensity (PLI) measurements on thin GaAs and InGaAs films to compare the surface recombination velocity at interfaces of the materials with AlAs and native oxide. An analytical expression for the internal quantum efficiency of the PLI method for thin semiconducting films is derived. This expression is applied to measurements on specially designed multilayer structures based on GaAs and InGaAs thin films. The results show that the native oxide on an In0.15Ga0.85As film has a one order of magnitude lower surface recombination velocity than the native oxide on a GaAs film.
