Energy band gapElectrical conductivitySilicon dioxide matrixIn this study, silicon nanocrystal (Si-nc) films were synthesized by compositing of Si-nc powder embedded in silicon oxide phase. The Si-nc film produced by the spin-coating methode using Tetraethylorthosilicate, ethanol, phosphoric acid, ...

This is in contrast to the behaviour of irradiated insulators (e.g., silicon dioxide10 and silicon nitride20). In what follows we prove that this effect can occur only for semiconductors with a band gap slightly smaller than the energy of the probing optical photon. In this case, the ...

A polymeric photonic band gap structure can be defined by a block copolymeric species, a mixture of homopolymers, or a combination optionally with appropriate dielectric contrast enhancing additives. The structure includes periodic, phase-separated microdomains alternating in refractive index, the domains...
Recently HfOhas attracted considerable attention as a gate dielectric for (CMOS) CMOS technology, because it combines a wide band gap and good thermal stability with a low-frequency dielectric constant much higher than that of SiO. While the exact values of the band gap and band alignment with...
31. A two-terminal, monolithic, tandem light emitting diode (LED) device comprising: a first layer of semiconductor material having an n-type region, a p-type region, and a first band-gap energy; a plurality of first layer LED sub-cells formed in the first layer and electrically connected...
The present invention employs hetero-structures, or hetero-junctions, having a plurality of band gap energy levels for increasing the forward-to-reverse current ratios of PN junctions. As used herein, the terms “hetero-structure” or “hetero-junction” mean a structure having at least first-typ...
