We report new and exciting experimental results on ion-induced nanopatterning of a-Si and a-Ge surfaces. The crystalline Si (100) and Ge (100) wafers were amorphized and an a/c interface was developed by pre-irradiation with a 50 keV Ar+ beam at normal incidence with an [...]

Silicon wafers can be supplied with specifications as found in: https://www.powerwaywafer.com/silicon-wafer
Silicon is a semiconductor material, and its resistivity is closely related to the doping concentration. Doping is that introducing a small amount of impurities into silicon crystals to alter their electrical properties. According to the [...]
