摘要: A composite photosensitive material of enhanced sensitivity to, and absorption of, incident radiation, wherein an array of particles of an electrically conducting material is embedded in and dispersed through a semiconducting matrix transparent to the wavelengths of interest, the particles having sizes of from about 1 to about 100 nanometers and having volume fractions of at least about 10 percent. The composite material is usable in photosensitive device applications such as detectors, photocells, photodiodes, and vidicons. Sensitivity to infrared radiation is particularly high where the matrix has a dielectric constant of at least about 10. The preferred particle material for enhanced infrared sensitivity is silver or gold, and the preferred matrix is silicon of CuInSe.sub.2.

摘要: An infrared external photoemissive detector can have an n-p heterojunction comprising an n-type semiconductor layer and a p-layer; the n-layer semiconductor comprising doped silicon embedded with nanoparticles forming Schottky barriers; and the p-layer is a p-type diamond film. The nanoparticles can be about 20-30 atomic percentage metal particles (such as silver) having an average particle size of about 5-10 nm. The p-layer can have a surface layer that has a negative electron affinity. The n-layer can be in the range of about 3 μm to 10 μm thick, and preferably about 3 μm thick. The doped silicon can be doped with elements selected from the list consisting of phosphorus and antimony.
