The experiment result shows, when extra magnetic field B=0, and supply voltage VDS is constant, inequipotential potentials VHO of the nc-Si/c-Si heterojunction MAGFET are close to zero output with increasing absolute value of the gate biased voltage VGS. Adopting gate biased voltage to compensate inequipotential potentials, compared with extra compensation resistance method, could improve magnetic sensor sensitivity, when supply voltage VDS is -1.0 V, magnetic sensitivity can be improved by 18%.

实验结果表明，当外加磁场B=0时，工作电压VDS恒定时，随栅极偏置电压VGS 绝对值增加，纳米硅/单晶硅异质结MAGFET不等位电势VHO逐渐接近零位输出；采用栅极偏置电压进行不等位电势补偿较外加补偿电阻方法可以使磁传感器灵敏度得到提高，在工作电压VDS为-1.0 V时磁灵敏度约提高18%。

For example: peripherin-layer is made of nuphtheroquinon-xylenediol azide-anti-alcohol (microspectroscopic catalysical sensitivity range of up to 320 ~ 460nm), PS print, when you choose to use iodine gallium light, exposure time, simply by 20s with high pressure mercury lamp above the 30s, because although the two lamps and the spectral 300 ~ 460nm scope, but sulfonylated spetroscopy gallium light emission from 400 nm wavelength in close to the section of the distribution of light energy and light energy than much of high pressure mercury lamp, uniform is also much larger, and with this kind of formulation-peripherin-catalysical spetroscopy, emiting anastomasis sensitivity more productive.
