Tunable light-emitting diode |
摘要 |
A light-emitting diode device includes a base substrate including a plurality of quantum well layers, a first electrode on one side of the plurality of quantum well layers, and a second electrode on an opposite side of the plurality of quantum well layers. The device includes a tensile-stressing layer formed on the base substrate and having a thickness and chemical composition configured to generate a first tensile stress in the base substrate, the first compressive stress selected to cause the base substrate to have a predetermined band-gap. |

1. A light-emitting diode device, comprising:
a base substrate including a plurality of quantum well layers, a first electrode on one side of the plurality of quantum well layers, and a second electrode on an opposite side of the plurality of quantum well layers; and a tensile-stressing layer formed on the base substrate and having a thickness and chemical composition configured to generate a first tensile stress in the base substrate, the first compressive stress selected to cause the base substrate to have a predetermined band-gap, wherein the tensile-stressing layer is a stress-inducing layer having a thickness and chemical composition configured to define a location of a fracture in a host substrate on which the base substrate is formed, the fracture formed in a spalling process. |
