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.\u003c\/p\u003e","brand":"Gardners","offers":[{"title":"Default Title","offer_id":52926673813783,"sku":null,"price":12080.49,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6918\/8119\/files\/9783030257156_73051e57-3f0f-4588-a192-51d21bb09b8c.jpg?v=1781598121","url":"https:\/\/payment.letskitaboo.com\/te\/products\/theory-of-electronic-and-optical-properties-of-atomically-thin-films-of-indium-selenide-9783030257156","provider":"Kitaboo One eStore","version":"1.0","type":"link"}
