Effects of Switching on the 2-DEG Channel in Commercial E-Mode GaN-on-Si HEMT

Micromachines
In this study, the effects of switching on the two-dimensional electron gas (2-DEG) channel in an E-mode GaN-on-Si HEMT are investigated using a GS-065-004-1-L device that is commercially available for educational practice.

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

p-GaN层厚度对GaN基p-i-n结构紫外探测器性能的影响

, 2008
研究了p-GaN层厚度对GaN基pin结构紫外探测器性能的影响.模拟计算表明:较厚的p-GaN层会减小器件的量子效率,然而同时也会减小器件的暗电流,较薄的p-GaN层会增加器件的量子效率,但是同时也增加了器件的暗电流.进一步的分析表明,金属和p-GaN之间的结电场是出现这种现象的根本原因.在实际的器件设计中 ...
