Abstract

Substrate structures and fabrication methods thereof. A substrate structure includes a bendable substrate and an inorganic electrode structure on the bendable structure, wherein the inorganic electrode structure includes a conductive layer or a semiconductor layer. The inorganic electrode structure includes carbon nanotubes, carbon nanofibers, a nanolinear material, or a micro-linear material. The bendable substrate includes polyethylene (PE), polyimide (PI), polyvinyl alcohol (PVA), or polymethyl methacrylate (PMMA).

Claims

1. A substrate structure, comprising:

a bendable substrate;

an inorganic electrode structure transferred from a transferring substrate onto the bendable substrate such that the inorganic electrode structure is indented into the bendable substrate, and a top surface of the inorganic electrode is level with a top surface of the bendable substrate;

a plurality of auxiliary electrodes on the bendable substrate and adhered with the inorganic electrode structure; and

a structural layer disposed on the inorganic electrode structure and between the auxiliary electrodes, wherein a top surface of the structural layer is coplanar with top surfaces of the auxiliary electrodes,

wherein the inorganic electrode structure comprises a conductive layer or a semiconductor layer, and

wherein the bendable substrate comprises polyethylene (PE), polyimide (PI), polyvinyl alcohol (PVA), or polymethyl methacrylate (PMMA).

2. The substrate structure according to claim 1, wherein the inorganic electrode structure comprises carbon nanotubes, or carbon nanofibers.
