Influence of the "second gap" on the transparency-conductivity compromise in transparent conducting oxides: an ab initio study

Viet-Anh Ha, David Waroquiers, Gian-Marco Rignanese +1

Transparent conducting oxides (TCOs) are essential to many technologies. These materials are doped (\emph{n}- or \emph{p}-type) oxides with a large enough band gap (ideally $>$3~eV…
