Recent improvement of silicon absorption in opto-electric devices

open access: yesOpto-Electronic Advances, 2019
Silicon dominates the contemporary electronic industry. However, being an indirect band-gap material, it is a poor absorber of light, which decreases the efficiency of Si-based photodetectors and photovoltaic devices.

Destruction of the Kondo effect in a multi-channel Bose-Fermi Kondo model

open access: yes, 2004
We consider the SU(N) x SU(kappa N) generalization of the spin-isotropic Bose-Fermi Kondo model in the limit of large N. There are three fixed points corresponding to a multi-channel non-Fermi liquid phase, a local spin-liquid phase, and a Kondo ...

Sputter Deposition of Transition Metal Oxides on Silicon: Evidencing the Role of Oxygen Bombardment for Fermi‐Level Pinning

open access: yesphysica status solidi (a), Volume 216, Issue 23, December 2019., 2019
Growth of transition metal oxides on oxidized silicon substrates opens the possibility for new device structures. Reactive sputtering of the oxide deteriorates the Si/SiO2 surface passivation. Decoupling the oxidation step from the sputter deposition of the metal can alleviate this difficulty and results in superior Si/SiO2/TMO junctions.

Improving interruption performance of mechanical circuit breakers by controlling pre‐current‐zero wave shape

open access: yesHigh Voltage, Volume 4, Issue 2, Page 122-129, June 2019., 2019
Mechanical circuit breakers (MCBs) are the limiting component for current injection HVDC circuit breakers. Improving their interruption performance reduces requirements for capacitance and inductance needed in the injection circuit and thus space use and costs.

Comparing of Self-Incompatibility and Cytoplasmic Male Sterility Systems for the performance of F1 hybrids in cabbage (Brassica oleracea var. capitata L.)

open access: yesElectronic Journal of Plant Breeding, 2016
Four cytoplasmic male sterile (CMS) and three self-incompatible (SI) lines of cabbage were used as females for crossing with four cabbage testers (males) as per line × tester mating design during 2012-13 to produce the F1 seeds of 28 hybrids.
