Nanohole Explained

Nanoholes are a class of nanostructured material consisting of nanoscale voids in a surface of a material. Not to be confused with nanofoam or nanoporous materials which support a network of voids permeating throughout the material (often in a disordered state), nanohole materials feature a regular hole pattern extending through a single surface. These can be thought of as the inverse of a nanopillar or nanowire structure.

Uses

Nanohole structures have been used for a variety of applications, ranging from superlenses produced from a metal nanohole array,^[1] to structured photovoltaic devices used to improve carrier extraction,^[2] and light absorption.^[3]

Nanohole structures are also extensively utilized for the creation of photonic crystals, particularly for creating photonic crystal waveguides.
