NEGF Quantum Simulation of Field Emission Devices

Recent studies of wide band-gap diamond field emission devices have realized superior performance and lifetime. However, theoretical studies using standard Fowler-Nordheim (FN) theory do not fully capture the physics of diamond semiconductor emitters as a result of the fitting parameters inherent to the FN approximation. The following research computationally models wide band-gap field emission...

Quantum-mechanical investigation of field-emission mechanism of a micrometer-long single-walled carbon nanotube.

A quantum-mechanical simulation is carried out to investigate the charge distribution and electrostatic potential along a 1 microm long (5,5) single-walled carbon nanotube under realistic field-emission experimental conditions. A single layer of carbon atoms is found sufficient to shield most of the electric field except at the tip where strong field penetration occurs. The penetration leads to...

Recent Developments in Non-perturbative Quantum Field Theory

In the last couple of years we have been witnessing a series of impressive results in the framework of two different but related types of quantum theories: supersymmetric Yang–Mills theories in four dimensions and superstrings. They have in common space-time supersymmetry. They also share the property that a formal perturbative expansion can be defined for these theories, and “renormalization” ...
