1200 V power Schottky silicon carbide diode

It is manufactured using a silicon carbide substrate. The wide band-gap material allows the design of a low V F Schottky diode structure with a 1200 V rating. Due to the Schottky construction, no recovery is shown at turn-off and ringing patterns are negligible

Emission and optical properties of SiO 2 /Si thin films

6/12/2016· The energy-band parameters and the emission and optical properties of SiO2/Si films of different thicknesses prepared by thermal oxidation and ion boardment are studied. It is shown that the band gap E g of the SiO2/Si film with a thickness of 30–40 Å is 8.8–8.9 eV. In the transition layer, the E g value and secondary-electron emission coefficient σm steadily decrease with increasing

Microscopic Heterogeneities in the Electrical Properties of …

We report on electric-field-tuning experiments of single chromophores in a transparent matrix on top of a microcrystalline layer of silicon carbide (SiC). Upon changes of the electric field strength, most single-molecule lines show a slow creeping behavior toward a new equilibrium position. We attribute the relaxations to slow charge rearrangements in the SiC on a (sub)microscopic scale. This

Potential and Development of Amorphous Silicon …

Amorphous silicon-carbide layers generally have a higher band gap (1.8 – 2.3 eV) compared to the commonly used, hydrogenated, pure amorphous-silicon a-Si:H (1.7 eV). The higher band gap leads to a lower parasitic light absorption, which makes it possible to obtain either a higher short-circuit current jsc or to use a larger a-SixC1x:H(n)-layer thickness and thus to get a higher Voc [3].
