Atomically flat palladium films grown on synthetic mica

Abstract

Atomically flat palladium thin films were heteroepitaxially formed on thermally stable synthetic fluorophlogopite mica [KMg 3 (AlSi 3 O 10 )F 2 ]. Depositing palladium films was performed by a simple deposition method using home-made palladium filament without oxygen plasma. Combination of X-ray diffraction and atomic force microscopy revealed that thermally stable synthetic fluorophlogopite mica allowed post annealing at 800 °C, resulting in formation of atomically flat twin single crystalline epitaxial Pd(111) films.
