Abstract

Design and Modelling of Single Molecular Switch with Graphene Electrodes

Rafsa Koyadeen T

The electronic transport properties of molecular device based on molecular switches with graphene electrode are investigated by density functional theory and nonequilibrium Green’s function. The devices with open and closed configurations show a switching effect. It is found that doping of different amounts of nitrogen atoms and boron atoms on left and right graphene electrodes results in different electronic transport properties. In addition, the observed oscillation of current in the devices induced by doping using transmission eigenstates and transmission spectra of the device. The local density of states of the device is calculated to analyze the observed rectifying behavior. The results suggest that doping of nitrogen atoms on the left electrode can be considered as a factor to modulate the electronic transport properties of molecular device.We would like to inform you that your manuscript “ The Impact of Covid-19 on the Mental Health and the role of Social Support” for the Journal of Clinical Schizophrenia & Related Psychoses ” has received positive review comments and with your acceptance we will go ahead for publication.
