Tauc-Lorentz Dispersion Formula - Horiba
WebThe Tauc plot method assumes that the absorption coefficient alpha is related to the energy band gap (Eg) by the following equation: alpha*hv = A (hv-Eg)^n. where A is a proportionality constant and n an index related to the specifical electronical transition (1/2 direct allowed; 3/2 direct forbidden; 2 indirect allowed; 3 indirect forbidden ... WebThe Tauc-Lorentz model requires εi to be zero for energies less than the band gap. Consequently, Tauc-Lorentz mod-el does not take into account intra-band absorption: any defect or intra-band absorption increases εi below the band gap and generates bad fits in that region. Valid spectral range The Tauc-Lorentz model well describes the ... kansas right to know
