Abstract:
1. A homo-material heterophased quantum well comprising: a first structural layer, a second structural layer and a third structural layer, wherein the second structural layer is sandwiched between the first and third structural layers, wherein the first structural layer, the second structural layer and the third structural layer are formed by growing atoms of a single material in a single growth direction, wherein the energy gap of the second structural layer is smaller than the energy gaps of the first and third structural layers, wherein the single material is Gallium Nitride, wherein the first structural layer is wurtzite structure, wherein the second structural layer is zinc-blende structure, wherein the third structural layer is wurtzite structure, wherein the wurtzite structure faces the single growth direction in a first direction, wherein the first structural layer comprises an atom A layer and an atom B layer interlinked with the atom A layer, wherein the atom A layer has a gallium atom layer and a nitrogen atom layer interlinked with the gallium atom layer, wherein the nitrogen atom layer faces the gallium atom layer in the first direction, wherein the zinc-blende structure faces the single growth direction in an eighth direction, wherein the second structural layer comprises a first atom A layer, an atom B layer, an atom C layer and a second atom A layer adjacent to the atom C layer, wherein the atom B layer of the second structural layer is sandwiched between the first atom A layer and the atom C layer, wherein the first atom A layer comprises a gallium atom layer having a gallium atom, wherein the second atom A layer comprises a gallium atom layer having a gallium atom, wherein the gallium atom of the gallium atom layer of the first atom A layer faces the gallium atom of the gallium atom layer of the second atom A layer in the eighth direction, and wherein the first direction, the eighth direction and the single growth direction are the same.
