The promotion of electrons from the valence band into conduction band in pure TiO2 by light absorption requires a photon with energy higher than 350
The promotion of electrons from the valence band into conduction band in pure TiO2 by light absorption requires a photon with energy higher than 350 nm. Calculate the band gap in this semiconductor. (The energy of a band gap is typically given in electron volts (V); 1 eV = 1.602 x 10-19j)
