Investigation of temperature dependence of radiation from semiconductor lasers and light emitting diodes
Abstract The investigation of temperature dependences of the radiation from red semiconductor laser diodes and light emitting diodes (LEDs) made on the basis of AlGaInP quadruple solid solution has been carried out. Despite the fact that the basic reasons for the change in the wavelength of laser an...
