Abstract:
1. A rod-like light-emitting device comprising: a semiconductor core of a first conductivity type having a rod shape, the rod shape having a length and a circumference; a semiconductor layer of a second conductivity type covering the semiconductor core so as to form a pn junction between the semiconductor core and the semiconductor layer coaxially with respect to the semiconductor core; and a transparent electrode formed so as to cover substantially a whole of the semiconductor layer, wherein the semiconductor core comprises an n-type semiconductor and the semiconductor layer comprises a p-type semiconductor, wherein an outer peripheral surface of a part of the semiconductor core is exposed along the entire circumference of the rod shape, the exposed part having a part of the length of the rod shape, and wherein the rod-like light-emitting device has a diameter within a range of from 10 nm to 5 μm, inclusive, and a length within a range of from 100 nm to 200 μm, inclusive.
