WebMar 2, 2006 · In N-channel MOSFETs, only electrons flow during forward conduction – there are no minority carriers. Switching speed is only limited by the rate that charge is supplied to or removed from capacitances in the MOSFET. Therefore switching can be very fast, resulting in low switching losses. This is what makes power MOSFETs so efficient at high ... WebP+ Si. The only problem is that the Schottky-S/D MOSFET would have a lower Id than the regular MOSFET if is too large to allow easy flow of carriers (electrons for NFET) from the source into the channel.
