#381 Constructing semiconductor device

There are two fundamental features that are indispensable elements in the making of the functional semiconductor device. First, it needs to be assured that the electric current can flow in and out of semiconductor comprising a device in the entirely undisturbed fashion. To accomplish this task, ohmic contacts need to be formed at the device input and output.


Assuming ohmic contacts are in place, second feature making active semiconductor device is building into it an ability to vary in the controlled fashion its resistance by applying bias voltage between device terminals. To accomplish this last feature a potential barrier must be built into the device structure. The most common way of accomplishing it is to form a p-n junction within semiconductor material.
