in this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (ldds-cntfet) with a negative differential resistance (ndr) characteristic, called negative differential resistance ldds-cntfet (ndr-ldds-cntfet). the device was simulated by using a non equilibrium green’s function method. to achieve this phenomenon, we have created...

Nonlinear electrical properties, such as negative differential resistance (NDR), are essential in numerous circuits, including memristors. Several physical origins have been proposed to lead the NDR phenomena semiconductor devices over last more than half a century. Here, we report behavior formation randomly oriented graphenelike nanostructures up 37 K and high on-current density ${10}^{5}\pha...

Electron transport properties of pure and Oxygen and/or Methyl substituted pyrene between two semi-infinite Aluminum atomic electrodes have been investigated by means of density functional theory plus the non-equilibrium green’s function method. The electrodes were represented by a slab of Al atoms oriented along the [111] plane. The computations were carried out in the bias voltage range of 0....
