We applied scanning internal photoemission microscopy (SIPM) to clarify the electrical characteristics on the electrode periphery of Ni/n-GaN Schottky contacts. Two types of Schottky contacts with different electrode formation methods were prepared.

Previously, we demonstrated that the Na-flux coalescence growth technique had high potential for the fabrication of large-diameter, high-quality GaN crystals. This present study investigates the relation between the flux composition (Ga/Na) and void

In this study, we investigated the growth of GaN polycrystals using the Al-added Na flux method. We studied the effects of Al on accelerating the nucleation and purity of GaN polycrystals. The yields of GaN crystals grown in Al-added Na flux were dra

In the big data era, many users upload data to cloud while security concerns are growing. By using attribute-based encryption (ABE), users can securely store data in cloud while exerting access control over it. Revocation is necessary for real-world

In our study, we found that threading dislocation density (TDD) in GaN crystals naturally reduced from ~10 9 cm −2 in a seed to less than ~10 3 cm −2 , just by using the small-sized seed called a “point seed”. However, the mechanism of the dr
