Material for forming a patterning coating comprising a phase-change material and devices incorporating the same

Abstract

A solid-solid phase-change material (PCM) for use as a patterning coating adapted to impact a propensity of an evaporated flux of a deposited material to be deposited thereon, the patterning coating for disposition on a first layer surface of an underlying layer in a first portion of a lateral aspect of an opto-electronic device, such that a deposited layer comprising the deposited material is deposited on a second portion of the lateral aspect, while the first portion is substantially devoid of a closed coating of the deposited material. An optic-electronic device comprising the solid-solid PCM.
