熱馳豫 的英文怎麼說
中文拼音 [rèchíyù]
熱馳豫
英文
thermal relaxation-
But for the furnace cooling samples, all samples have another damping peak about at 3 00 ( called tp2 peak ). the peak is not of relaxation model, the peak temperature does not vary with frequencies
除爐冷試樣外，其餘各熱處理態試樣均在300左右，有一內耗峰幾2峰，此內耗峰無馳豫特性。頻率變化，內耗峰的位置不變，對同一熱處理態試樣內耗峰位置不變。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。
