Intrinsic absorption coefficient
WebJul 5, 2024 · III. Absorption of Light and Generation. 5. Diffusion Current. 1. Absorption Coefficient and Penetration Depth. Now that we’ve studied carrier transport, and the way in which current flows through doped semiconductors, we can now discuss how semiconductors absorb photons from sunlight and generate free charge carriers. WebAmbient temperature photoluminescence spectra accounted for four emission bands in the visible spectral region due to the presence of various intrinsic defect centres in the films. The non-linear absorption coefficient (β eff ) were estimated by open aperture Z-scan technique and found to be in the order of 10 −2 (cm/W) and indicates a positive …
