Silicon light-emitting device and display apparatus employing the same
A silicon light-emitting device and a display device employing the silicon light-emitting device are provided. In the silicon light-emitting device, a doped region is ultra-shallowly doped with the opposite type dopant to the type of the substrate on one side of the substrate, so that the p-n junction between the doped region itself and the substrate creates luminance by annihilation combination of electron-hole pairs due to the quantum confinement effect. At least one semiconductor material portion at least partially forms a stack along with the doped region on the other side of the substrate. First, second, and third electrodes are formed for electric connection. The silicon light-emitting device includes a transistor of at least one step and accordingly performs current amplification and/or switching. Thus, luminance can be driven just with a small amount of current. In addition, when an array of silicon light-emitting devices is adopted in a display device, the turn-on and turn-off durations for used current can be controlled on a pixel-by-pixel basis. Therefore, the luminance duration can be easily controlled.
