Abstract(in English) | We have investigated an Al_xMo_<1-x> alloy as an ohmic electrode material to obtain a thermally stable ohmic electrode with low contact resistance. The novel metallization scheme of Al_<0.9>Mo_<0.1>/n-InP demonstrated an ohmic characteristic without regard to annealing. It was found that the ohmic behavior was correlated to the diffusion of Al with Mo into the InP substrate, forming thin AlInP layer at the InP interface. A simple estimation using the model-solid theory predicted a small band discontinuity between InP and the strained AlInP layer. This is one of possible reasons for the observed ohmic characteristics. It was also suggested that Al-Mo bonds forming the Al_<12>Mo intermetallic compound or its precursor proceed the exchange reaction between Al and In atoms into the InP substrate. |
