| 简介 |
A III-N on silicon LED constructed to emit light in the visible range includes a layer of single crystal III-N with a light emitting diode formed therein and designed to emit light at a first wavelength through a lower surface, a REO-Si template mated to the layer of single crystal III-N and designed to approximately crystal lattice match a silicon substrate, and a light emission layer of rare earth oxide selected to receive and absorb light at the first wavelength, up-convert the absorbed light, and re-emit light at a second wavelength in the visible range. The lower surface of the REO-Si template is either mated to the upper surface of a crystalline silicon substrate with the light emission layer integrated into the REO-Si template or mated to an upper surface of the light emission layer with a lower surface of the light emission layer mated to the crystalline silicon substrate. |
