Nanoelectronic devices are being extensively developed in these years with a large variety of potential applications. In this article, some recent developments in nanoelectronic devices, including their principles, structures and potential applications are reviewed. As nanodevices work in nanometer dimensions, they consume much less power and function much faster than conventional microelectronic...
In this work, we have performed a Monte Carlo (MC) simulation to study the THz response of two types of nanometer devices at room temperature, so called three terminal Y-Branch Junction (YBJ) and Ballistic Deflection Transistor (BDT. This sub-millimeter frequency range in the electromagnetic spectrum is attracting more and more interest due to its broad range of applications, from medical diagnostic...
In this paper we discuss the effect of decoherence induced by electron-phonon scattering at room temperature in nanoscale devices where quantum transport effects play an important role as the RTD and the nano-MOSFET. The analysis is carried out from results of quantum Monte Carlo simulation based on the Wigner's function formalism. It puts forward the scattering-induced localization of electrons and...
By introducing a broken geometric symmetry in a semiconductor nanochannel, we have realized an array of planar nano-diodes, called a self-switching device (SSD), using only one nanolithography step. Not only being much simpler than conventional diodes which generally require a multi-layer architecture and multi-step lithography, the SSD also possesses a very high operational speed because of the simplicity...
