Query: Tunnel Field-Effect Transistors in 2D Transition Metal Dichalcogenide
  Materials   In this work, the performance of Tunnel Field-Effect Transistors (TFETs)
based on two-dimensional Transition Metal Dichalcogenide (TMD) materials is
investigated by atomistic quantum transport simulations. One of the major
challenges of TFETs is their low ON-currents. 2D material based TFETs can have
tight gate control and high electric fields at the tunnel junction, and can in
principle generate high ON-currents along with a sub-threshold swing smaller
than 60 mV/dec. Our simulations reveal that high performance TMD TFETs, not
only require good gate control, but also rely on the choice of the right
channel material with optimum band gap, effective mass and source/drain doping
level. Unlike previous works, a full band atomistic tight binding method is
used self-consistently with 3D Poisson equation to simulate ballistic quantum
transport in these devices. The effect of the choice of TMD material on the
performance of the device and its transfer characteristics are discussed.
Moreover, the criteria for high ON-currents are explained with a simple
analytic model, showing the related fundamental factors. Finally, the
subthreshold swing and energy-delay of these TFETs are compared with
conventional CMOS devices.
