The practical use of tunnel field-effect transistors is retarded by the low on-state current. In this paper, the energy-band engineering of InAs/Si heterojunction and novel device structure of source-pocket concept are combined in a single tunnel field-effect transistor to extensively boost the device performance. The proposed device shows improved tunnel on-state current and subthreshold swing. In addition, analytical potential model for the proposed device is developed and tunneling current is also calculated. Good agreement of the modeled results with numerical simulations verifies the validation of our model. With significantly reduced simulation time while acceptable accuracy, the model would be helpful for the further investigation of TFET-based circuit simulations.

AlGaN/GaN -based heterostructure field-effect transistors (HFETs) with and without Mg -doped semi-insulating carrier confinement layer were simulated by using ISE TCAD software, respectively. The detailed study on the electrical properties of these samples was performed. The effect of inserting Mg -doped GaN layer on the source–drain (S–D) leakage current was investigated. Higher values of drain current and extrinsic transconductance were achieved with conventional HFETs (without Mg -doped). The source-to-drain (S–D) leakage current of conventional HFETs was also higher. However, the S–D leakage current was reduced with the insertion of the Mg -doped semi-insulating carrier confinement layer. Our results are in good agreement with the experimental results obtained by other researchers.

In this paper, analytical modelling and performance analysis of novel device structures such as single gate SOI Tunnel Field Effect transistor (SG SOI TFET), Dual-Material Gate TFET (DMG TFET) and Dual Material Double Gate TFET (DMDG TFET) are proposed. The performance of the three devices is studied and compared in terms of surface potential, electric field and drain current. The DMDG TFET shows better performance in suppressing leakage current and enhancing ION current than the SG SOI TFET and DMG TFET. The analytical models of the devices are found to be in good agreement with the results obtained using two-dimensional TCAD device simulator.
