摘要: | Two different kinds of n-type GaN films were prepared by organometallic vapor phase epitaxy, one by using trimethylgallium (TMGa) and another by using triethylgallium (TEGa) as the alkyl source. Schottky diodes with well-behaved current-voltage and capacitance-voltage characteristics were fabricated. Deep-level transient spectroscopy studies were performed on these samples. Three distinct deep levels, labeled E1, E2, and E3, were measured in the film grown with TMGa, with an activation energy of 0.14, 0.39, and 1.63 +/- 0.3 eV, respectively. Only one level, E3, was observed in the film prepared with TEGa. (C) 1995 American Institute of Physics. |
