The original MOSFET (metal–oxide–semiconductor field-effect transistor, or MOS transistor) was invented by Egyptian engineer Mohamed M. Atalla and Korean engineer Dawon Kahng at Bell Labs in 1959, and demonstrated in 1960. Kahng went on to invent the floating-gate MOSFET with Simon Min Sze at Bell Labs, and they proposed its use as a floating-gate (FG) memory cell, in 1967. This was th… Webb5 juni 2013 · A heterostructure of aluminum gallium nitride (AlGaN) and then GaN is grown on the AlN. This layer provides a foundation on which to build the eGaN FET. A very thin AlGaN layer is then grown on top of the highly resistive GaN. It is this thin layer that creates a strained interface between the GaN and AlGaN crystals layers.
WebbThe first ultrathin oxide-nitride (O-N) gate dielectrics with oxide equivalent thickness of less than 2 nm have been deposited and characterized in n-MOSFET's. The O-N gates, …
