The theory of tunneling and resonant tunneling is reviewed. Experimental justification of this theory was provided by an InP-based RTD with room-temperature PVR = 12. Its valley current was well-modeled as the sum of thermionic emission through the second resonance and a temperature-independent scattering/defect component. ZnS and CaF2 were experimentally considered as epitaxial barrier materia...

This paper presents the calibration of novel kinetic velocity model (KVM) in drift-diffusion (DD) transport approach, which can account for ballistic effect short-channel devices. The KVM considers a thermionic emission limit and free carrier acceleration mobility. We develop methodology to extract parameters high-field saturation SiGe nanowires over whole mole fraction range. calibrated DD sim...

Vacuum triodes have been scaled down to the microscale on a chip by microfabrication technologies be vacuum transistors. Most of reported devices are based field electron emission, which suffer from problems unstable poor uniformity, and high requirement for operating vacuum. Here, overcome these problems, transistor field−assisted thermionic emission individual carbon nanotubes is proposed fab...

A general model is presented for electron emission yield from planar photocathodes that accounts for arbitrary cathode thickness and finite recombination velocities at both front and back surfaces. This treatment is applicable to negative electron affinity emitters as well as positive electron affinity cathodes, which have been predicted to be useful for energy conversion. The emission model is...
