Light Emission Produced by Current Injected into a Green Silicon-Carbide Crystal

Abstract: This paper deals with the light emission, which arises from the passage of a current in the forward direction over a ^-w-barrier in a transparent ("pure") silicon-carbide crystal. The results differ from previous results obtained on a dark blue (impure) silicon carbide crystal in several respects: The spectral distribution of light emission is found to be independent of current and temperature. Both the efficiency of light emission and the decay constant of light emission increase exponentially with decreasing… Show more

“…4 that in SiC-based light-emitting diodes (LEDs) the photon energy about 2 eV is observed at the diode voltage of 1.8 V, and it was noticed that this process can be accompanied with some cooling of the device. In GaAs LEDs, this situation is quite usual [5,18], and the "refrigerating power" Q per junction area unit was discussed.…”

“…[1][2][3]. The phenomenon of the optical refrigeration is known in semiconductors after a number of early studies [4][5][6]. There are serious problems with laser cooling of semiconductors, and it became an interesting topic of the luminescence physics and technology.…”

“…The thermoelectrical pumping effects in LEDs of various wavelength were also observed and reported by experimentalists. [10][11][12][13] The first observation of η W P E > 1 is reported in 2012 when Santhanam et al used lock-in measurement tools to demonstrate an infrared GaInAsSb/GaSb LED with η W P E over 200% at 135 • C. 1 In 2013, higher-than-unity η W P E was achieved in mid-infrared LEDs at room temperature. 14 All these ultra-efficient LEDs operated at extremely low bias (qV kT ), and their output power densities were merely several hundreds nW/cm 2 , which is not enough for direct observation of temperature drop.…”
