strained crystal 中文意思是什麼
strained crystal
解釋
應變晶體-
Using domestic strained integrated resistor as weighing sensor, at89c52 single chip as control unit, combined with arithmetical magnification, analogtodigital conversion ( a / d ), real time clock, liquid crystal display ( lcd ), and series communication interface, a minitype automatic weighing lysimeter is developed. that made measurement of evapotranspiration become conveniently and effectively in studying on water use of crops
為了方便、有效地測定植物的蒸散，為水分利用研究提供價廉物美、簡單易用的儀器，本研究利用國產的集成電阻應變式稱重傳感器，採用at89c52單片機作為控制單元，結合運算放大、模數轉換、實時時鐘、液晶顯示、數據存儲、串列通信等外圍介面電路，研製了小型自動稱重式蒸散儀。 -
As is known to all, one of the most important characteristics of sige hbt is the strained sige base growing on the si substrate. generally, the base is required to be very thin so as not to cause the base sige crystal lattice mismatching in subsequent annealing process. also, in order not to increase the thermal noise of device, the base is always heavily doped
眾所周知， sigehbt的主要特點之一就是在si材料襯底上生長的sige材料是應變的，為了在後續的高溫退火工藝中不發生晶格馳豫現象，通常要求器件的基區要做的很薄，同時為了不增加器件的熱噪音，通常sigehbt基區都是高摻雜的。
