Mosfet pinch off energy band
http://web.mit.edu/6.012/www/SP07-L9.pdf WebFor a Si channel in a MOSFET the effective mass equation reads. Since the device is uniform in the у direction, the potential energy along у can be taken as that of a very wide quantum well of width W and of a constant deep potential, as shown in figure 7.18a. The potential energy along x will be of the same form as that used in the solution of the …
