Effects of microstructures on hydrogen induced cracking of electrochemically hydrogenated double notched tensile sample of 4340 steel
(
Elsevier Ltd
, 2016 , Article)
Quantitative fractographic characteristics of 4340 steel is demonstrated for a grain size range of 10-100 ?m and hardness range of 41-52 HRC. Double-notched tensile samples were electrochemically charged in-situ with ...
Time-resolved photocurrent spectroscopic diagnostics of electrically active defects in AlGaN/GaN High Electron Mobility Transistor (HEMT) structure grown on Si wafers
(
American Scientific Publishers
, 2016 , Article)
Time-resolved photocurrent (TRPC) spectroscopy with a variable-wavelength sub-bandgap light excitation was used to study the dynamics of the decaying photocurrent generated in the heterostructures of the AlGaN/GaN high ...
