Epitaxial Growth of Bis(dimethylglyoximato)platinum(II) Accompanied by Hole Formation

Abstract

High-resolution transmission electron microscopy was performed to evaluate the crystallinity of bis(dimethylglyoximato)platinum(II) (Pt(dmg) 2 ) grown on KCl and KBr substrates. Although the epitaxial orientations of the Pt(dmg) 2 thin films grown on the KCl and KBr substrates were nearly identical, the crystallinity of the individual crystalline domains varied. A misfit between Pt(dmg) 2 and KBr based on a point-on-line coincidence was thought to have affected the crystallinity of the deposited thin film. Some of the Pt(dmg) 2 crystals that formed on the KBr substrate contained holes due to defects. Careful selection of a substrate with a small misfit value is important for obtaining highly crystalline epitaxial thin films.
