WebLooking for online definition of TAUC or what TAUC stands for? TAUC is listed in the World's largest and most authoritative dictionary database of abbreviations and … WebGenerally, for amorphous materials, the allowed indirect electron transitions according to the Tauc equation are valid. In the case of optical absorption, for low photon energy ranged between 10 2 and 10 4 cm −1, the absorption coefficient follows Urbach’s law. This is the width of the band tails of the localized states from the valence band.
