摘要：

Solar-blind AlGaN Schottky photodiodes with a large active area of 2 x 2 mm have been fabricated on a AIN/sapphire template. The resulting devices show dark current density as low as 6.6 x 10(-11) A at -5 V bias. A zero-bias peak responsivity of 38 mA/W was obtained at 260 nm, corresponding to. an estimated detectivity of 1.2 x 10(14) cm Hz(1/2) W-1.
