Improved drain current characteristics of tunnel field effect transistor with heterodielectric stacked structure

In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel r...

A theoretical description of gate tunnel current in an MOS transistor is proposed, and the results of calculations for the case of an n-channel MOSFET with extremely thin gate oxides are given. A comparison of the gate tunnel current with the drain current is made.

Performance Analysis of Double Hetero-gate Tunnel Field Effect Transistor

A hetero gate dielectric low band gap material DG Tunnel FET is presented here. The investigated device is almost free from short channel effects like DIBL and t V rolloff. Simulation of the device characteristics shows significant improvement over conventional double gate TFET when compared interms of on current, ambipolar current, roll-off, miller capacitance and, device delay time. Simulatio...

Design and Simulation of a Dual Material Double Gate Tunnel Field Effect Transistor Using Tcad

High leakage currents and short channel effects become significant enough to be the major concerns for circuit designers as semiconductor devices are miniaturized. Tunnel field effect transistor(TFET) show good scalability and have very low leakage current .These transistors have very low leakage current, good sub-threshold swing, improved short channel characteristics and lesser temperature se...
