Abstract

The electronic transport property of tungsten nitride nanoribbon-based molecular device is investigated using density functional theory. The study on electronic transport properties are discussed in terms of device density of states and transmission spectrum of the nanoribbon. The scattering region of the nanoribbon is placed between the electrodes. For different bias voltages, the transport properties are studied. The contribution due to various orbitals leads to the peak maximum in device density of states. The transmission spectrum and transmission pathway provides insight to the transmission of charge under various bias conditions. The maximum peak in the transmission spectrum corresponds to the variation in transmission of charge with different bias voltage. The reported results will pave the way to improve the performance in the field of nanoelectronics.
