A physics-based cutoff frequency model considering high-injection heterojunction barrier effects in SiGe HBTs is derived. Compared with other compact modeling approaches, the present model accurately captures the cutoff frequency behavior at very high current densities for SiGe HBTs with deep Si-SiGe heterojunctions. The model also offers better insight into the charge density distribution under K...... hiện toàn bộ

Rare-earth-doped GaN switchable color electroluminescent devicesIEEE Transactions on Electron Devices - Tập 49 Số 9 - Trang 1545-1551 - 2002
J. Heikenfeld, A.J. Steckl
Switchable color (SC) light emission has been obtained from thin-film electroluminescent devices (ELDs) which use green Er- and red Eu-doped GaN phosphors. These two-electrode SCELDs can switch color through variation of applied bias. Different SCELD structures, which share in common a stacked GaN: Er/GaN: Eu phosphor layer, can be implemented for use with DC or AC operation. A single SCELD can em...... hiện toàn bộ
