第一句(为了看着方便我把它拆成一句一句得了):There is a certain voltage VGS at which the hole population immediately under the oxide-silicon interface will be identical to that deep within the bulk of the crystal.
2:Under such conditions,a bang diagram representing conditions from the interface to the interior of the P-type silicon crystal would have perfectly horizontal band edges.
3:This magic gate-bias value is termed the flat-band voltage,VGS=VFB,and is valuable as a conceptual starting poing.
4:When the gate terminal is now made more positive with respect to source ,the band edges begin to bend near the oxide-silicon interface.
5:This matter will be examined in detail.
6:At the moment,what is important is that potential ys at the surface of the silcon crystal is becoming more positive through the influence of the fild plate.
7:Hole density at the interface declines and electron density rises.
8:This is dictated by the law of mass action,pn=ni^2,because the silicon remains at equilibrium.
9:The reason for the caveat is that any leakage current through the oxide is accompanied by a net current in the silicon that violates equilibrium.
10:But the superb insulating qualities of SiO>2(这个是二氧化硅)-resistivity in excess of 10^15 ohm.cm-make a vanishing concern at present.
