What does it mean for metal to be p-type or n-type?
WebMar 1, 2024 · The CTLM tests showed that the p-GaAs contacts were both typical ohmic contact before and after annealing, and the smallest specific contact resistivity of 4.8×10⁻⁶Ω·cm² was obtained after... WebSep 7, 2024 · The semiconductor should be uniformly doped with donors or acceptors as p-type or n-type semiconductors. The semiconductor (Si) should be thick enough for charges to encounter a field free region (Si bulk) before reaching the back contact. The Ohmic contacts should be established on the backside of the MOS device. peace corps retirement benefits
