We have found microgrooves on the (001) β -Ga _2 O _3 epitaxial deposited by halide vapor-phase epitaxy in Schottky barrier diodes to be killer defects at the point of reverse leakage-current flow [−10.0 μ A at −64 V]. The microgrooves tended t

This study elucidates the dislocation responsible for the leakage current in a halide vapor phase epitaxial (001) β-Ga2O3 Schottky barrier diode. A high reverse leakage current of −0.98 μA was observed at −100 V as an emission pattern via ultra

The elimination of killer defects, which are responsible for the reverse leakage current and breakdown at low voltage in β-gallium oxide (β-Ga2O3) Schottky barrier diodes (SBDs), is crucial for the commercialization of the power devices. We found p

We utilized ultra-high sensitive emission microscopy to investigate the origin of reverse leakage current of edge-defined film-fed grown (001) β-Ga2O3 Schottky barrier diodes. In the emission patterns, we observed a partially appearing void, having

RecQ5 is a member of the RecQ family of DNA helicases. There are 5 RecQ members in humans. Defects in 3 of them, i.e., BLM, WRN, and RTS, cause Bloom, Werner, and Rothmund-Thomson syndromes, respectively. RECQL1 and RECQL5 have not been associated wi

Drosophila melanogaster RecQ5, a member of the RecQ family, is expressed in early embryos. The loss of maternally-derived RecQ5 leads to spontaneous mitotic defects in syncytial embryos. We demonstrate that the mitotic defects are derived from anapha
