According to an embodiment, a nitride semiconductor Schottky diode includes a first layer including a first nitride semiconductor and a second layer provided on the first layer and including a second nitride semiconductor having a wider band gap than the first nitride semiconductor. The diode also includes an ohmic electrode provided on the second layer and a Schottky electrode provided on the second layer. The second layer includes a region containing an acceptor in the vicinity of the Schottky electrode between the Schottky electrode and the ohmic electrode. |
