Claim Text:
1. A light-emitting element comprising: an insulating layer provided on a semiconductor substrate; a first electrode for implanting electrons and a second electrode for implanting holes, the first and second electrodes being provided on the insulating layer; and a light-emitting portion electrically connected to the first and second electrodes and composed of a thin film extending in parallel with a surface of the semiconductor substrate on the insulating layer, wherein the thin film is composed of either a silicon crystal or a germanium crystal and has such a film thickness that light is emitted by implantation of the electrons and holes, wherein the thin film includes two regions in which holes are disposed at a predetermined interval in a longitudinal direction in vicinities of the first and second electrodes, respectively, and wherein a gap between adjacent holes of the two regions in which holes are disposed is equal to or less than 10 nm.
