We have discovered large linear electro‐optics (Pockels) effect in ZnO crystalline films doped with fluorine and deposited on bare glass. A complex approach including self‐consistent band structure calculations together with a Car‐Parinello molecular dynamics simulation of the film–glass interface structure was used. The non‐centrosymmetric charge density distribution between the ZnO–F wurtzite‐like crystalline films and the bare glass substrate causes the observed Pockels effect.
