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\u003cbr\u003e","brand":"None","offers":[{"title":"Couverture souple","offer_id":46280985149650,"sku":"9783030257170","price":160.95,"currency_code":"CAD","in_stock":true},{"title":"Couverture rigide","offer_id":46280985182418,"sku":"9783030257149","price":160.95,"currency_code":"CAD","in_stock":true},{"title":"Livre numérique Kobo","offer_id":46280985215186,"sku":"b3624a66-d80c-3f7b-93be-fe41735a4fef","price":116.09,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/8980\/5233\/files\/1_f85836a0-b8bb-4798-97b8-78fb8986f680.jpg?v=1763681038","url":"https:\/\/www.indigo.ca\/fr\/products\/theory-of-electronic-and-optical-properties-of-atomically-thin-films-of-indium-selenide","provider":"Indigo","version":"1.0","type":"link"}
