Here we essentially rearrange the atomic components of well-known bulk semiconductors into periodic assemblies of nanometer-dimension, single-size, and single-shape clusters, housed inside a crystalline nanoporous host material. This method yields a class of nanomaterials considered to be a semiconductor cluster crystal, an expanded semiconductor or a semiconductor quantum supralattice, which we call an endosemiconductor. If instead the atomic constituents of a bulk semiconductor are juxtaposed into the form of an open-framework nanostructure, the class of material obtained is considered to be a crystalline nanoporous semiconductor or a framework semiconductor, which we call an exosemiconductor. 关键词: POLY(METHYL-3-THIOPHENE); IN SITU AFM; STRUCTURE MODIFICATION; SEMICONDUCTOR QUANTUM SUPRALATTICE; ZSM-5 ZEOLITE FILM; POROUS SILICON; NONSTOICHIOMETRIC SILVER; SODIUM HALOSODALITES; OPTICAL-PROPERTIES; NONSTOICHIOMETRIC SILVER; SODIUM HALOSODALITES; OPTICAL-PROPERTIES; SODALITES; CLUSTERS; DOTS; SPECTROSCOPY SODALITES; CLUSTERS; DOTS; SPECTROSCOPY
