该大好还是小好？应该多稳定？谢谢咯。 |

发帖数: 49 | 2 If you refer to flat band voltage in MOS/MOSFET, it is a negative voltage
applied between the metal and semiconductor to achieve flattening of the
bands.
It is determined by two factors: the work function difference between metal
and s/c and charges in the oxide. You may find the formula for calculation
in any fundamental mosfet books.
If you're targeting for a normally-off MOSFET(Vth>0), it's better to have a
flat band voltage of smaller absolute value. For example, you may choose a
gate contac

of semiconductor devices.
