Nanoholes are a class of nanostructured material consisting of nanoscale voids in a surface of a material. Not to be confused with

nanofoam Nanofoams are a class of nanostructured, porous medium, porous materials (foams) containing a significant population of pores with diameters less than 100 nanometer, nm. Aerogels are one example of nanofoam. Metal Overview Metallic nanofoams ...

nanoporous Nanoporous materials consist of a regular organic or inorganic bulk phase in which a porous structure is present. Nanoporous materials exhibit pore diameters that are most appropriately quantified using units of nanometers. The diameter of pores i ...

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

Uses

Nanohole structures have been used for a variety of applications, ranging from

superlenses A superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution depending on the illumination ...

produced from a metal nanohole array, to structured photovoltaic devices used to improve carrier extraction, and light absorption. Nanohole structures are also extensively utilized for the creation of

photonic crystals A photonic crystal is an optical nanostructure in which the refractive index changes periodically. This affects the propagation of light in the same way that the structure of natural crystals gives rise to X-ray diffraction and that the atomic ...

, particularly for creating photonic crystal

waveguides A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency wav ...
