)) amongst the source and also the drain, even at very very low electrical discipline. The channel is sandwiched by big bandgap barrier products (SiGe or Si) to decrease the leakage. In this case, the Ge channel is biaxially compressive-strained with the barrier levels. The barrier layers ought to also provide a VBO sufficiently high to confine holes Within the Ge channel. A modulation doping layer, divided by spacer or barrier layer, eliminates the ionized impurity scattering with holes inside the Ge channel.
Because it looks no solitary dielectric content can reach everything needed for an outstanding gate stack, composite gate stacks deliver some much required overall flexibility, in addition to several remarkable and unexplored opportunities for Ge gate stack style.
