Integrated conductive substrate, and electronic device employing same

Abstract

Provided are an integrated conductive substrate simultaneously serving as a substrate and an electrode, and an electronic device using the same. The integrated conductive substrate includes a conductive layer containing iron, which has a first surface having a first root mean square roughness, and a semiconductor layer containing a semiconductor material, which has a second surface having a second root mean square roughness and is formed on the first surface. Here, the semiconductor layer includes a semiconductor-type planarization layer formed by a solution process using at least one of the semiconductor material and a precursor of the semiconductor material to planarize the first surface of the conductive layer, and the second root mean square roughness is smaller than the first root mean square roughness.
