如何得知DEVICE裡材料的電阻率(resistivity)


#1

您好:

一直有一個疑問, 最近在使用上也必須知道, DEVICE可以仿真得到電流, 我們要如何得知仿真時不同材料的電阻率(resistivity, ohm-cm)呢? 基本上這和塊材的背景參雜(background doping)有關, 我們要如何得知呢?

感謝

参见这个例子
The resistance of the slab can be simulated by adding a “test” contact that connects to the waveguide on the same side of the slot as one of the two contacts, such that a continuous circuit is formed through the silicon (the “anode_test” contact in the project is added for this purpose).
对于常用的材料,例如,在微波线路中,其基底材料的电阻率或者Z0都是已知的。
