The thesis shows how the electronic propertes of 2D InSe vary significantly with film thickness, changing from a weakly indirect semiconductor for the monolayer to a direct gap material in the bulk form, with a strong band gap variation with film thickness predicted and recently observed in optical experiments. The proposed theory is based on a specially designed hybrid k.p tight-binding model approach (HkpTB), which uses an intralayer k.p Hamiltonian to describe the InSe monolayer, and tight-binding-like interlayer hopping. Electronic and optical absorption spectra are determined, and a detailed description of subbands of electrons in few-layer films and the influence of spin-orbit coupling is provided. The author shows that the principal optical excitations of InSe films with the thickness from 1 to 15 layers broadly cover the visible spectrum, with the possibility of extending optical functionality into the infrared and THz range using intersubband transitions. .Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Surfaces (Physics)Interfaces (Physical sciences)Thin filmsSolid state physicsMathematical physicsSurface and Interface Science, Thin Filmshttps://scigraph.springernature.com/ontologies/product-market-codes/P25160Solid State Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25013Theoretical, Mathematical and Computational Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19005Surfaces (Physics).Interfaces (Physical sciences).Thin films.Solid state physics.Mathematical physics.Surface and Interface Science, Thin Films.Solid State Physics.Theoretical, Mathematical and Computational Physics.530.41Magorrian Samuel Jauthttp://id.loc.gov/vocabulary/relators/aut838598BOOK9910349513703321Theory of Electronic and Optical Properties of Atomically Thin Films of Indium Selenide1873096UNINA
