Abstract
A nitride semiconductor structure includes a nitride semiconductor layer having a principal plane and including a nitride semiconductor. The normal to the principal plane of the nitride semiconductor layer is inclined at 5 degrees or more and 17 degrees or less with respect to the [11-22] axis of the nitride semiconductor constituting the nitride semiconductor layer in the direction of the +c-axis of the nitride semiconductor. The nitride semiconductor structure may further include a substrate having a principal plane which supports the nitride semiconductor layer on the principal plane. The substrate may include any one selected from the group consisting of a nitride semiconductor, sapphire, and Si.
