| 1 | Study of enhancement-mode GaN pFET with H plasma treated gate recess显示文摘This letter showcases the successful fabrication of an enhancement-mode(E-mode)buried p-channel GaN fieldeffect-transistor on a standard p-GaN/AlGaN/GaN-on-Si power HEMT substrate.The transistor exhibits a threshold voltage(VTH)of−3.8 V,a maximum ON-state current(ION)of 1.12 mA/mm,and an impressive ION/IOFF ratio of 10^(7).To achieve these remarkable results,an H plasma treatment was strategically applied to the gated p-GaN region,where a relatively thick GaN layer(i.e.,70 nm)was kept intact without aggressive gate recess.Through this treatment,the top portion of the GaN layer was converted to be hole-free,leaving only the bottom portion p-type and spatially separated from the etched GaN surface and gateoxide/GaN interface.This approach allows for E-mode operation while retaining high-quality p-channel characteristics. | Xiaotian Gao Guohao Yu Jiaan Zhou Zheming Wang Yu Li Jijun Zhang Xiaoyan Liang Zhongming Zeng Baoshun Zhang | 2023 | Journal of Semiconductors2023，44，11： | 0 |
| 2 | Risk-constrained Energy Management Strategy for a Commercial Campus Considering Comprehensive Reserves Against Islanding Conditions显示文摘This paper proposes an optimal risk-constrained energy management strategy for commercial buildings in a commercial campus with islanding capabilities.The goal is to minimize the total operation and maintenance costs,while maximizing comprehensive comfort levels for the occupants.A two-stage riskconstrained,scenario-based stochastic optimization approach is adopted to handle various uncertainties associated with the energy management process,such as power generation of rooftop solar panels,arrival state-of-charges,and arrival/departure time of plug-in electric vehicles,intermittent load demand,and uncertain grid-connection conditions.A conditional-valueat-risk method is introduced to provide a risk-averse energy management strategy.To face the challenge of both reducing the computational burden and maintaining the accuracy of the stochastic programming,an advanced scenario reduction method is leveraged.Extensive simulation results validate the effectiveness of the proposed energy management strategy for minimizing total operating and maintenance costs of commercial buildings with islanding capabilities,while maximizing comprehensive comfort levels of the occupants. | Zheming Liang Desong Bian Xiaohu Zhang Di Shi | 2023 | CSEE Journal of Power and Energy Systems2023，9，5： | 0 |
