目前已有研究使用Rb、Cs、Sr、Ba等碱或碱土元素来钝化SiO2/4H-SiC界面以提升4H-SiC MOSFET μfe. 其工艺流程为先在SiC上沉积一层非常薄的碱或碱土材料, 然后沉积栅氧化物, 并在O2或O2/N2环境下进行退火. 如图7(a)所示, 虽然使用Rb和Cs只产生了大约25 cm2 V–1 s–1的μfe峰值, 但使用Sr和Ba...
Programmable logic controllers (PLCs) use a simple form of programming in order to exercise control functions. This program involves drawing each step in a program as the rung on a ladder, each rung then being taken in turn from top to bottom. Each rung can execute logic switching functions...

The Intergovernmental Panel on Climate Change (IPCC) states that material substitution could be used to reduce global CO2 emissions, for example, the addition of by-products or waste materials (GGBS/FA) to clinker (Metz et al. 2007). Portland-limestone cements (PLCs) have not been included ...
The distance between the electrodes can be increased, the area of the electrode can be reduced, or a low dielectric constant material used for passivation can reduce capacitance. 3. Results 3.1. Matching the Measured and Simulated Data Obtained from the Basic T-Gate HEMT In this study, we ...
A novel low turnoff loss carrier stored (CS) silicon-on-insulator (SOI) lateral insulated gate bipolar transistor (LIGBT) with trench gate barrier (CS SOI TGLIGBT) is proposed. The proposed CS SOI TGLIGBT features a trench gate inserted between the pwell and n-drift. Firstly, the trench ...
