Selective metal deposition on organic surfaces for device applications

Abstract

Selective metal deposition signifies that metal vapor atoms are deposited on a hard organic surface but not on a soft (low glass transition temperature) surface. This paper introduces the origin, extension, and device applications of selective metal deposition. A photochromic surface shows the light-controlled selective metal deposition phenomenon, but the surface material is not essential to it; various organic surfaces including organic crystal and polymer surfaces can be used. We demonstrate the applications of selective metal deposition, including cathode patterning for organic light-emitting devices, micro thin-film fuses, and multifunctional diffraction grating. Selective metal deposition can be applied to a variety of electric and optic devices.
