First-principles studies on electronic transport properties of CdS nanoribbon based molecular device

The electronic transport properties of cadmium sulfide nanoribbon based molecular device were investigated by employing first principles calculation using density functional theory. The electronic properties are discussed in terms of density of states spectrum and electron density. The density of states of charge depends on the applied bias voltage. The electron density is seen more at cadmium sites. The transport properties of CdS nanoribbon are studied using transmission coefficient spectrum and transmission pathways. The electronic transmission all along the scattering region depends on the bias voltage; depending upon the bias voltage the transmission path also gets altered. The information provided in the present study will pave way to tailor nanostructures with improved performance in nanoelectronic devices.
