Graphene-Based Periodic Gate Field Effect Transistor Structures for Terahertz Applications

We report on theoretical investigation of graphene based Field Effect Transistor (FET) structures for resonant absorption of terahertz (THz) radiation by the plasmons excited in the high sheet concentration and high carrier mobility active layers. Metallic grating gates with varying periods were used to couple the THz radiation into the plasmons in the active region of the devices. Such grating...

Graphene Nano-Ribbon Field Effect Transistor under Different Ambient Temperatures

This paper is the first study on the impact of ambient temperature on the electrical characteristics and high frequency performances of double gate armchair graphene nanoribbon field effect transistor (GNRFET). The results illustrate that the GNRFET under high temperature (HT-GNRFET) has the highest cut-off frequency, lowest sub-threshold swing, lowest intrinsic delay and power delay product co...

Field-effect tunneling transistor based on vertical graphene heterostructures.

An obstacle to the use of graphene as an alternative to silicon electronics has been the absence of an energy gap between its conduction and valence bands, which makes it difficult to achieve low power dissipation in the OFF state. We report a bipolar field-effect transistor that exploits the low density of states in graphene and its one-atomic-layer thickness. Our prototype devices are graphen...

Field-effect transistor on SrTiO3 with sputtered Al2O3 gate insulator

Electrical visualization of chemo-mechanical signal transduction using a smart gel-modified gate field effect transistor.

A field effect transistor (FET) whose gate surface has been modified with a stimuli-responsive "smart" polymer gel can visualize the kinetics of the chemo-mechanical signal transduction as a mode of its altered electrical characteristics without any labels.
