摘要
Light-emitting diodes (LEDs) were fabricated on the basis of GaInAsSb alloys grown from lead-containing solution-melts. Electroluminescence characteristics and their current and temperature dependences were studied. The external photon yield at room temperature was 1.6 and 0.11% for LEDs with emission wavelengths lambda = 2.3 and 2.44 mum, respectively. For LEDs with emission wavelength lambda = 2.3 mum, the average emission power P = 0.94 mW was attained in the quasi-continuous mode at room temperature. In the pulsed mode, the peak radiation power was P = 126 mW at a current of 3 A, a pulse duration of 0.125 mus, and a frequency of 512 Hz. (C) 2004 MAIK "Nauka / Interperiodica".
