Comparative assessment of III-V heterostructure and silicon underlap DG-MOSFETs, is done using 2D Sentaurus TCAD simulation. III-V heterostructure device has narrow-band In0.53Ga0.47As and wide-band InP layers for body, and high-K gate dielectric. Density gradient model is used for simulation and interface traps are considered. Benchmarking of simulation results show that III-V device provides higher on current, lesser delay, lower energy-delay product and lower DIBL than silicon device. However III-V device has higher SS and lower Ion/Ioff than silicon device. The results indicate that there is a need to optimize the Ion/Ioff, SS and DIBL values for specific circuits.
