摘要： A diamond semiconductor device of the present invention comprises an n-type diamond layer to which an n-type dopant is doped at high concentration so that metal conduction dominates, a p-type diamond layer to which a p-type dopant is doped at high concentration so that metal conduction dominates, and a high resistance diamond layer formed between the n-type diamond layer and the p-type diamond layer. Here, the thickness and the doping concentration of the high resistance diamond layer are values at which semiconductor conduction dominates. Then, in a case that an applied voltage is forward bias, electrons are injected from the n-type region to the p-type region through the conduction band of the high resistance region, and holes are injected from the p-type region to the n-type region through the valance band of the high resistance region, so that a current flows. On the other hand, in a case that an applied voltage is reverse bias because substantially no dopant is doped to the high resistance diamond layer, carriers are not present, so that a large current does not flow. Therefore, semiconductor conduction dominates as carrier conduction in pn junction and the rectification can be obtained, so that with the control of carriers, good diode characteristics or transistor characteristics can be achieved.
摘要翻译：本发明的金刚石半导体器件包括n型金刚石层，以高浓度掺杂n型掺杂剂以使金属导电占主导地位，p型掺杂剂掺杂在高的p型金刚石层浓度使得金属导电占主导地位，并且在n型金刚石层和p型金刚石层之间形成高电阻金刚石层。这里，高电阻金刚石层的厚度和掺杂浓度是半导体传导占主导地位的值。然后，在施加的电压为正向偏压的情况下，通过高电阻区域的导带从n型区域向p型区域注入电子，从p型区域注入空穴 n型区域通过高电阻区域的价带，使得电流流动。另一方面，在施加的电压为反向偏压的情况下，由于基本上没有掺杂剂掺杂到高电阻金刚石层，所以不存在载流子，使得大的电流不流动。因此，半导体传导作为pn结中的载流子导通，可以获得整流，因此通过载流子的控制，可以实现良好的二极管特性或晶体管特性。
