Band gap diode

웹The emission wavelengths of light emitting diodes and laser diodes are largely determined by the band gap energy. The higher that energy, the shorter the wavelengths. Note that the strongest emission occurs at photon … 웹2010년 7월 23일 · Silicon’s bandgap is just wide enough so that electrons can easily cross it once they are hit by photons of visible light. The same process also works in reverse. When electricity passes through a semiconductor, it can emit a photon, whose color is determined by the material’s bandgap. That’s the basis for light-emitting diodes, which are ...
