摘要：
The contact made between a semi-insulating semiconductor and a metal (Schottky diode) or a low resistance semiconductor (bipolar diode) often gives an Ohmic I-V characteristic. This can be explained by standard relaxation semiconductor theory without the need for any special assumptions and the electrical properties can be predicted. These include the measured material resistivity, the temperature coefficient, the departures from the Ohmic character and possible negative capacitance effects. There are technological implications for devices using semi-insulating materials, such as MESFETs. (C) 1998 Elsevier Science Ltd.
