The physical mechanism of the time, emitter lateral dimension (AE) and low-high temperature dependent degradation under mixed-mode stress for C-doped SiGe HBTs (SiGe:C HBTs) on thin-film silicon-on-insulator (SOI) is investigated. We focus on the impact of mixed-mode stress on device characteristics such as base current (IB) and current gain (β) degradation rate, device scaling issue and low-high...
YBCO coated conductors are candidate materials for future electric power devices such as transmission cables, transformers, and fault current limiters. In practical applications, YBCO coated conductors are subject to short-circuit fault currents greater than the operating current. These fault currents cause heat generation, resulting in degradation of the characteristics of YBCO coated conductors...
