Fig. 20. (a) Anode voltage versus anode current density characteristics of the proposed SiC-based LED, illustrating its electrical behavior. (b) Relationship between current density and luminous power output, indicating the electroluminescent efficiency of the device. (c) CIE 1931 chromaticity diagram showing the emission color coordinates corresponding to different active layers, including pristine SiC, KSi, and CaSi. The plot highlights the color tunability of the LED through specific dopant incorporation.
