Under pulse condition, charging and discharging of surface states between gate and drain induce gan hemt current collapse
脈沖條件下， ganhemt電流崩塌效應主要由柵漏之間表面態充放電引起。 -
In this paper, the theory of negatively charged surface states is used to investigate dynamic breakdown characteristics and the increase of gate - drain breakdown voltage as well as the reduction of saturated drain - source current after sulfur passivation. the measure which can improve the stability of sulfur passivation is proposed
本論文通過對gaasmesfet擊穿機理和硫鈍化機理的研究，用負電荷表面態理論，解釋了gaasmesfet動態擊穿特性及硫鈍化后柵漏擊穿電壓增大、源漏飽和電流減小的機理，提出了改善硫鈍化穩定性的措施。 -
Flooding occurs when rainfall is so high that natural or engineered drainage fails to drain away the surface runoff. floods are usually fairly transient in the urban areas
當降雨率超過天然或人造排水系統的負荷時，積聚地面的雨水便不能及時排去，因而引致水浸。 -
As a result, the fermi level at the surface will shift towards the valence band maximum ( vbm ). accordingly the band bending increases, and the surface depletion layer thickness enhances, therefore, the channel thickness reduces. this is the main factor resulting in the decrease of saturated drain - source current
表面費米能級向價帶頂移動，能帶彎曲加劇，肖特基勢壘高度增加，表面耗盡層變厚，導電溝道變窄，是導致源漏飽和電流下降的主要因素。 -
The alteration procedure of the underground water level is simulated under drizzle and storm rainfall conditions respectively adopting the coupling fem analysis program of surface flow and subsurface flow. the numerical simulation of the underground water level shows that the drain ditch installed over the slope does not have an notable effect on the underground water level
利用降雨條件下地表水入滲和產流耦合的計算程序，模擬了小降雨強度和大雨強度對地下水位變化的影響，並用數值計算給出了地表排水溝對地下水變化的影響不是很顯著的結論。 -
Quasi - static capacitance has been measured, when drain voltage is 0v, and gate voltage changes from ? 5v to 0v, the surface peak
採用應力測試方法，獲得了algan / ganhemt漏極電流隨時間的變化。 -
The result of the test for dynamic breakdown characteristics reveal that breakdown voltage increases as the lengths of the pulses applied to the gate and drain electrodes increase. this could be mainly due to the influence of surface states
Gaasmesfet動態擊穿特性測試結果表明， gaasmesfet的擊穿電壓隨柵極與漏極上所加脈沖電壓寬度的增大而增大，這主要是因為表面態的原因。 -
Namely, the electric field at the drain - side edge of the gate decreases with the increasing of negative charge density in the surface, so the breakdown voltage of gaas mesfet ' s will increase
表面受主態的增多使表面負電荷密度增大，表面聚集的負電荷可以分散漏側柵邊緣處的電力線密度，減弱了柵靠漏一側的電場強度，擊穿電壓提高。 -
