Abstract
According to one embodiment, a nitride semiconductor includes a nitride member. The nitride member includes a first nitride region, and a second nitride region. The first nitride region includes AlGaN (0≤x1<1). The AlGaN includes a first element. The first element includes at least one selected from the group consisting of Fe and Mn. The second nitride region includes AlGaN (0≤x1<1). A direction from the first nitride region to the second nitride region is along a first direction. A second lattice length of the second nitride region in a first axis crossing the first direction is different from a first lattice length of the first nitride region in the first axis.
