Abstract
Doping-less tunnel field effect transistor (DLTFET) based on charged plasma (CP) concept has emerged as an energy-efficient transistor for low-power analog/RF and digital applications. With that in mind, we investigate a Si0.6Ge0.4/Ge heterojunction DLTEFT with a high-κ dielectric (HJ HD DLTFET). In this device, the drain is made up of Si0.6Ge0.4 and source, and the channel is made up of Germanium. Additionally, a high-κ dielectric (TiO2) has been used to suppress off-state current and provide better insulation. Moreover, a comparative analysis is performed between conventional DLTFET and HJ HD DLTFET using the ATLAS device simulator. The simulation results for HJ HD DLTFET offers an improvement in on-state current (~1000 μA/μm), improved ION/IOFF ratio (~1014), and subthreshold swing (~36.14 mV/decade) at 1.5 V of the gate voltage (VG) and 0.3 V of the drain voltage (VD). The distinguishable characteristics demonstrated by HJ HD DLTFET recommends its competence in low-voltage and low-power analog/RF applications.
