Numerical Study of Single-Electron Resonant Tunnelling via a Few Ionised Donors in Laterally Confined Resonant Tunnelling Diodes

Resonant Tunnelling Optoelectronic Circuits

Nowadays, most communication networks such as local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs) have replaced or are about to replace coaxial cable or twisted copper wire with fiber optical cables. Light-wave communication systems comprise a transmitter based on a visible or near-infrared light source, whose carrier is modulated by the information sign...

A primer for resonant tunnelling

Resonant tunnelling is studied numerically and analytically with the help of a three-well quantum one-dimensional time-independent model. The simplest cases are considered where the three-well potential is polynomial or piecewise constant.

Decay of an inhomogeneous state via resonant tunnelling

We recently investigated the nature of resonant tunnelling in standard scalar Quantum Field Theory, uncovering the conditions required for resonance. It was shown that whereas the homogeneous false vacuum may decay via bubble nucleation, it may not decay in a resonant fashion. The no-go theorem given there is circumvented in this study by considering an initial state other than the homogeneous ...

Resonant tunnelling diodes based on molecular wires incorporating saturated spacers: a quantum-chemical study

The demand for increased miniaturization of integrated circuits has opened the way to the emerging field of molecular electronics. Recent experimental studies have established that single molecules or a finite ensemble of self-assembled molecules can perform the basic functions of conventional electronic components (i.e., transistors, wires and diodes). In particular, it has been demonstrated t...
