Patent ID: 8895958

Claim:
A light emitting element comprising: a group IV semiconductor substrate that has a (111) surface and is doped with a first conductivity type; an insulating film, which has a plurality of openings, and covers the (111) surface of the group IV semiconductor substrate; a plurality of core-multishell nanowires, formed of III-V compound semiconductors and arranged on the insulating film; a first electrode connected to the group IV semiconductor substrate; and a second electrode, connected to the side surfaces of the core multishell nanowires, for covering the side surfaces of the core-multishell nanowires, wherein each of the core-multishell nanowires includes a center nanorod, formed using a III-V compound semiconductor of the first conductivity type and extended upward from the (111) surface of the group IV semiconductor substrate through one of the openings, a first barrier layer, formed using a III-V compound semiconductor of the first conductivity type that has a bandgap greater than that of the III-V compound semiconductor used to form the center nanorod, for covering the side surfaces of the center nanorods on the insulating film; a quantum well layer, formed using a III-V compound semiconductor that has a bandgap smaller than that of the III-V compound semiconductor used to form the first barrier layer, for covering the first barrier layer; a second barrier layer, formed using a III-V compound semiconductor of a second conductivity type, which differs from the first conductivity type, that has the same composition as the III-V compound semiconductor used to form the first barrier layer, for covering the quantum well layer, and a capping layer, which has a layer formed of a III-V compound semiconductor of the second conductivity type, and covers the second barrier layer to enable a connection to the second electrode by ohmic contact, wherein, in the plurality of core-multishell nanowires, a gap between the side surfaces of the adjacent core-multishell nanowires is filled with the second electrode for covering the side surfaces of the adjacent core-multishell nanowires and an insulator or a semi-insulating semiconductor located between the second electrodes.
