The Effect of the Pillar Ripple on the Reverse Recovery in Superjunction MOSFETs
Power Electronic Devices and Components, 2022 Fast dI/dt and oscillations often are the causes of failure during the reverse-recovery of superjunction MOSFETs. These issues become more prominent with shrinking the pitch size of the superjunction in an attempt to improve the overall performance from ...

"Reversed" alamethicin conductance in lipid bilayers
Biophysical Journal, 1991 Alamethicin at a concentration of 2 micrograms/ml on one side of a lipid bilayer, formed at the tip of a patch clamp pipette from diphytanoyl phosphatidylcholine and cholesterol (2:1 mol ratio) in aqueous 0.5 M KCl, 5 mM Hepes, pH 7.0, exhibits an asymmetric current-voltage curve, only yielding alamethicin currents when the side to which the peptide ...
