1) shrinkage
变窄
2) wide to narrow
宽变窄
3) bandgap narrowing
禁带变窄
1.
The bandgap narrowing is distributed between the conduction and valence bands,according to the Jain-Roulston model,and its effects on the currents of abrupt AlGaAs/GaAs HBTs including the self-heating effect,are analyzed.
基于禁带变窄量在导带和价带之间的分布比例与掺杂浓度相关的Jain-Roulston模型,研究了重掺杂能带结构的变化对突变异质结HBT电流影响。
4) gain narrowing
