Process for the thickness growth of colloidal nanosheets and materials composed of said nanosheets

摘要

A process of growth in the thickness of at least one facet of a colloidal inorganic sheet, by sheet is meant a structure having at least one dimension, the thickness, of nanometric size and lateral dimensions great compared to the thickness, typically more than 5 times the thickness. The process allows the deposition of at least one monolayer of atoms on at least one inorganic colloidal sheet, this monolayer being constituted of atoms of the type of those contained or not in the sheet. Homostructured and heterostructured materials resulting from such process as well as the applications of the materials are also described. By homostructured is meant a material of homogeneous composition in the thickness and by heterostructured is meant a material of heterogeneous composition in the thickness.
