DC Green Electroluminescence of Al-CuGaS2 Diode
View through CrossRef
The dc green electroluminescence (EL) spectra observed at the Al-CuGaS2 diode are described over the temperature range of 100-220 K. The EL is just correspondent with the main EL of the Al-ZnS-CuGaS2 heterojunction diode. This confirms our previous proposal for the green EL from the Al-ZnS-CuGaS2 heterojunction diode that it originates from the CuGaS2 crystal, not from the ZnS film. Some possibilities for the electron injection from the Al electrode are also discussed in association with the current-voltage characteristics.
