Microelectronics Tutorial: Extrinsic Semiconductors

Concentrations of electrons and hole are small found in intrinsic semiconductors. As a result, the currents are small as well. We can increase these concentrations by adding some impurities to the semiconductor crystal. We’d like to have the impurity atom have a different number of valence electron than the semiconductor crystal. Also, we want the [...] . . . → Read More: Microelectronics Tutorial: Extrinsic Semiconductors

Microelectronics Tutorial: Semiconductor Materials and Properties

Electronic devices such as transistors and diodes are fabricated using semiconductor materials. Here, we briefly look at the properties and characteristics of semiconductors. We’ll introduce some terminology associated with semiconductors. Below is a short video on the crystal structure of silicon, carbon, and germanium _____________________________________________________ The crystallization of silicon, carbon (in the modification diamond) and [...] . . . → Read More: Microelectronics Tutorial: Semiconductor Materials and Properties
