价带顶 meaning in English

value band edge

Effective masses at the top of valence band and at the bottom of conduction band are deduced from the band structure
价带顶和导带底的有效质量从计算得到的能带结构中求出。
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
表面费米能级向价带顶移动，能带弯曲加剧，肖特基势垒高度增加，表面耗尽层变厚，导电沟道变窄，是导致源漏饱和电流下降的主要因素。
