【Abstract】 In this article the electric characteristics of semi-insulating GaAs with two metal contacts (MSM) are calculated, including the distributions of the space-charge density and of electron and hole conductivities for different electron and hole-supplying contacts with different bias voltages. On the basis of calculated results, the bias voltage dependence of the space charge region near the MS interface and its effects on the currentvoltage (I-V) characteristics of this structure are analyzed.更多还原
