InAsP/InAs nanowire heterostructure field effect transistors

In English We here show simulation results that by including a small InAsP heterostructure barrier inside the channel of a InAs nanowire transistor it is possible to increase both the sub threshold slope and on-off ratio with only a modest decrease in the drive current for a fixed gate overdrive. The design is based on the fact that the sharp InAsP heterostructure induces a small barrier in the conduction band and locally increases the bandgap, independent of the applied drain voltage
