abstract: 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 ...

A self-consistent solution of Schrödinger equation based on Green’s function formalism coupled to a two-dimensional Poisson’s equation for treating the electrostatics of the device is used to simulate and model the ballistic performance of an armchair edged GNRFET. Our results take into account interactions of third nearest neighbors, as well as relaxation of carbon–carbon bonds in the edges of...

Despite the simplicity of the hexagonal graphene structure formed by carbon atoms, the electronic behavior shows fascinating properties, giving high expectation for the possible applications of graphene in the field. The Graphene Nano-Ribbon Field Effect Transistor (GNRFET) is an emerging technology that received much attention in recent years. In this paper, we investigate the device performan...

In recent years, graphene has received so much attention because of its superlative properties and potential to revolutionize electronics, especially in VLSI. This study analyzes the effect single-event upset (SEU) an SRAM cell, which employs a metal-oxide semiconductor type nano-ribbon field transistor (MOS-GNRFET) compares results with another cell designed using PTM 10 nm FinFET node. Our si...

This paper introduces a new design of penternary inverter gate based on graphene nanoribbon field effect transistor (GNRFET). The penternary logic is one of Multiple-valued logic (MVL) circuits which are the best substitute for binary logic because of its low power-delay product (PDP) resulting from reduced complexity of interconnects and chip area. GNRFET is preferred over Si-MOSFET for circui...

Combination of high-mean free path and scaling ability makes graphene nanoribbon (GNR) attractive for application of field-effect transistors and subject of intense research. Here, we study its behaviour at high bias near and after electrical breakdown. Theoretical modelling, Monte Carlo simulation, and experimental approaches are used to calculate net generation rate, ionization coefficient, c...

Transistor makes up the cornerstone of modern computing. In this work, a SPICE model GNRFET was used to simulate performance NMOS and CMOS binary full adder. The adder evaluated in terms its average power consumption propagation delay. Three variables, namely resistance value, dimer lines channel length were manipulated impact on assessed. It observed that linear improvement delay accompanied b...

The present paper casts light upon the performance of an armchair graphene nanoribbon (AGNR) field effect transistor in the presence of one-dimensional topological defects. The defects containing 5-8-5 sp(2)-hybridized carbon rings were placed in a perfect graphene sheet. The atomic scale behavior of the transistor was investigated in the non-equilibrium Green's function (NEGF) and tight-bindin...
