Abstract (in Japanese) (See Japanese page) 
(in English) High Hall electron mobility and its high performances of Schottky barrier diodes on edge-defined film-fed grown (2 &#773;01) &#61538;-Ga2O3 single crystals have been demonstrated. High electron mobility of 886 cm2/V/s at 85 K, and 153 cm2/V/s at 300 K. Temperature dependence of electron mobility was fitted by theoretical values for specific scattering mechanisms, and we found that the electron mobility for > 200K is limited by optical phonon scattering and for < 100 K by ionized impurity scattering. On the high-purity crystal, we have fabricated Schottky barrier diodes with Ni Schottky contacts. The current density of forward voltage of 70.3 A/cm2 at 2.0V was obtained and a Schottky barrier height of 1.25 eV and nearly idea ideality factor of 1.01 were extracted.
