An ultra-high density data storage and retrieval unit has a phase-change layer for storing and retrieving data and at least one other layer. The phase-change layer and/or the other layer comprises a two-dimensional material, primarily one of the chalcogen-based materials. The data storage and retrieval unit may have a structure selected from a group consisting of the following configurations: 2-D film/2-D substrate 2-D film/non-2-D substrate non-2-D film/2-D substrate 2-D film/2-D film/X 2-D film/non-2-D film/X non-2-D film/2-D film/X wherein (1) the 2-D film and 2-D substrates are mostly chalcogen-based 15 materials, (2) the 2-D film, 2-D substrate, non-2-D film and non-2-D substrate are a semiconductor, metal, or insulator, and (3) the term X is a subst rate or film made of a material that is (a) 2-D or non-2-D and (b) metal, semiconductor or insulator. The data storage and retrieval unit may be included as a part of a photodiode, cathododiode, phototransistor, cathodotransistor, photoconductor, cathodoconductor, photoluminescent device, and/or cathodoluminescent device. |
