surface depletion layer meaning in English

表面耗尽层

Surface depletion layer and its influence on the corrosion morphology for aiuminum - linthium alloys containing cerium
铈对铝锂合金表面贫化层及其腐蚀形态的影响
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。
