Systematic Study of Fermi‐Level Pinning at Crystalline Metal/GaN Interfaces: First‐Principles Calculations and Diode Characterization

open access: yesRare Metals, EarlyView.
ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...

考虑火电深度调峰的电力系统低碳发电优化研究

open access: yes全球能源互联网, 2019
在低碳电力的背景下,风电接入系统成为节能减排的有效途径,基于此,电力系统加大火电机组调峰深度,增大下调备用空间,将是应对风电出力不确定性的重要举措之一。基于转子的低周疲劳损耗,建立火电机组深度调峰(deep peak regulation, DPR)的寿命损耗成本模型;考虑机组深度调峰引起的碳排放增量和不同碳排放区间下碳交易价格系数的变化,建立阶梯型碳交易成本模型;以总成本最低为目标,建立电力系统低碳优化调度模型。基于算例分析证明所提方法的合理性与有效性。
