Effects of hydrostatic pressure and temperature on the AlGaN/GaN High electron mobility transistors

In this paper, drain-source current, transconductance and cutoff frequency in AlGaN/GaN high electron mobility transistors have been investigated. In order to obtain parameters of exact AlGaN/GaN high electron mobility transistors such as electron density, the wave function, band gap, polarization charge, effective mass and dielectric constant, the hydrostatic pressure and temperature effects a...

Performance Study and Analysis of Heterojunction Gate All Around Nanowire Tunneling Field Effect Transistor

In this paper, we have presented a heterojunction gate all around nanowiretunneling field effect transistor (GAA NW TFET) and have explained its characteristicsin details. The proposed device has been structured using Germanium for source regionand Silicon for channel and drain regions. Kane's band-to-band tunneling model hasbeen used to account for the amount of band-to...

Highly doped thin-channel GaN-metal–semiconductor field-effect transistors

We report on the influence of the channel doping on dc, high frequency, and noise performance of GaN metal–semiconductor field-effect transistors ~MESFETs! grown on sapphire substrates. The devices with the channel thicknesses from 50 to 70 nm and doping levels up to 1.5310 cm were investigated. An increase in the channel doping results in the improved dc characteristics, higher cutoff, and max...

Ballistic (n,0) Carbon Nanotube Field Effect Transistors' I-V Characteristics: A Comparison of n=3a+1 and n=3a+2

Due to emergence of serious obstacles by scaling of the transistors dimensions, it has been obviously proved that silicon technology should be replaced by a new one having a high ability to overcome the barriers of scaling to nanometer regime. Among various candidates, carbon nanotube (CNT) field effect transistors are introduced as the most promising devices for substituting the silicon-based ...
