![]() We find that the monolayers exhibit noticeably different properties from the multilayered or the bulk system, with a markedly increased band gap that is, however, compromised by the presence of localized surface states. In order to understand the thickness-dependent optical and electrical properties, we have calculated the electronic structures of mono- and multiple layers (bulk) of CuSbS 2 using the hybrid functional method (HSE 06). The changes in optical properties with layer thickness down to monolayers have been studied. Eventually, these prolate-like structures form mesocrystals by oriented attachment crystal growth. At the initial stage the nanoplates grow laterally to form nanosheets as the primary structure, followed by their folding and attachment through homoepitaxy to form prolate-like secondary structures. Time-dependent TEM studies provide important insights into the growth mechanism of mesobelts. The latter can be exfoliated by Li-ion intercalation and sonication to obtain layers down to monolayer thickness. These include a colloidal bottom-up approach for the synthesis of CuSbS 2 nanoplates with thicknesses from six layers to several layers, and a hybrid bottom-up-top-down approach for the formation of CuSbS 2 mesobelts. We have for the first time developed solution-based approaches for the synthesis of mono-, few-, and multiple layers of CuSbS 2. Copper antimony sulfide (CuSbS 2) is a ternary layered semiconductor material that has been considered as an absorber material in thin film solar cells due to its optimal band gap (∼1.5 eV) with high absorption coefficient of over >10 4 cm –1. Kant insisted that we can never know the noumena, for we can never get beyond phenomena.Layered materials with controlled thickness down to monolayer are being intensively investigated for unraveling and harnessing their dimension-dependent properties. He resolved the four antinomies by drawing a distinction between phenomena (things as they are known or experienced by the senses) and noumena (things in themselves see noumenon). Kant’s “Copernican Revolution” was that things revolve around the knower, rather than the knower around things. Kant used the first two antinomies to infer that space and time constitute a framework imposed, in a sense, by the mind. Similarly, he offered proofs both for and against the three propositions: (1) that every complex substance consists of simple parts (2) that not every phenomenon has a sufficient “natural” cause ( i.e., that there is freedom in the universe) and (3) that there exists a necessary being, either within or outside the universe. He offered alleged proofs of the two propositions that the universe had a beginning and is of finite extent (the thesis) and also of a contrary proposition (the antithesis). Immanuel Kant, the father of critical philosophy, in order to show the inadequacy of pure reason in the field of metaphysics, employed the word antinomies in elaborating his doctrine that pure reason generates contradictions in seeking to grasp the unconditioned.
