Abstract
Provided embodiments are a thin film including a support material and nano particles having different density from that of the support material, and a method for manufacturing the same. Due to the density difference, the nano particles are intensively concentrated on an upper or lower part of the support material. The inventive concept also discloses a thin film capable of increasing surface roughness and a method for manufacturing the same. The thin film includes a support material, and particles contained therein. The particles may have lower density than that of the support material, and increase surface roughness at an upper part of the support material.
Claims19
A thin film comprising:
- a support material, and particles contained therein,
- wherein a density of the particles is different from that of the support material, and the particles are intensively concentrated on an upper or lower part of the support material.
A method for manufacturing a thin film, comprising:
- preparing a substrate;
- coating particles and a precursor solution of a support material having a different density from that of the particles on the substrate;
- and
- generating the support material from the precursor solution after the particles are re-arranged on an upper or lower part of the precursor solution due to the density difference.
