Computational methods shine light on conducting oxide transparency

By / January 20, 2012

Band structure of rutile SnO2, illustrating free-carrier absorption. Visible light does not carry enough energy to excite carriers across the band gap (a) or to excite free carriers directly to the next conduction-band states (b). However, additional momentum provided by a phonon enables indirect free-carrier absorption (c) for any visible or infrared wavelength. States in…
