WebTAUC PLOT The band gap energy can be determined using the TAUC relation [8-13]. It is a convenient way of studying the optical absorption spectrum of a material. According to the TAUC relation, the absorption coefficient α for material is given by 𝛼ℎṿ = 𝐴 (ℎṿ − 𝐸𝑔)𝑛, Where 𝐸𝑔 the band gap, constant A is ... WebApr 13, 2024 · The Tauc’s optical band-gap associated with the thin films can be determined by extrapolating the linear trend observed in the spectral dependence of (αhν) 2 and (αhν) 1/2 over a finite range of photon energies (hν) . The bandgap energy value of Tauc is obtained from the intersection of the linear portion of the curve with the abscissa .
