AlGaN/GaN MOS-HEMTs with Corona-Discharge Plasma Treatment
The effects of a corona-discharge plasma treatment on the performance of an AlGaN/GaN metal-oxide-semiconductor high-electron mobility transistor fabricated onto Si substrates were studied. The threshold voltage shifted from −8.15 to −4.21 V when the device was treated with an Al2O3 layer. The leakage current was reduced from 2.9 × 10−5 to 4.2 × 10−7 mA/mm, and the ION/IOFF ratio increased from...
متن کاملaqueous phase thiosulfate removal using photo catalysis
removal of thiosulfate (s2o32-, 200 mg/l) from simulated wastewater samples was investigated under varying co-pollutants and ph conditions employing the titanium dioxide (tio2) mediated photocatalysis. for thiosulfate only studies higher substrate removal was noted at lower ph with a specific trend of ph 4 > ph 7 > ph 10. furthermore, near complete thiosulfate removal was also achieved at ph 4....
متن کاملHeating the solar corona by plasma loops
We investigate the heating of the corona via plasma loops. It is shown that it may be possible to maintain the high corona temperatures using plasma loops as conduits. Under certain conditions heat can flow across magnetic fields up temperature gradients, a mechanism that has been previously applied to the heating of plasma loops. A typical conduit loop is hotter than the ambient plasma in the ...
