We showed that; charge carrier relaxation channels are affected when deposing graphene on polar substrates. Thus, the fundamental physical mechanisms controlling the ultra-fast dynamics in graphene are influenced by the choice of polar substrate, temperature, charge carrier density, and the thickness of the graphene\/polar substrate interface. The significant role of collinear and ultrafast scattering, enabling Auger processes, including charge multiplication, is a key to improving photovoltaic production and high sensitivity photo-detectors. In addition, we have shown that surface phonons of polar substrates produce an electric field that interacts with the electrons of the monolayer graphene deposited above. Indeed, the ESOP interaction causes a resonant coupling between the electron sublevels and the surface vibration modes inducing the increase of the Rabi splitting of the electrons energy levels in monolayer graphene on polar dielectrics.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786203024654\"\u003e\u003ch3\u003eAuger and electron-surface optical phonon interaction processes in monolayer graphene deposited on polar substrates.\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786203024654","offer_id":39455720046685,"sku":"9786203024654","price":54.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ddba2488-cfdb-4b83-a0e9-8b4771befd21.jpg?v=1773124250","url":"https:\/\/shop.autorenwelt.de\/products\/electron-phonon-interaction-in-graphene-polar-substrate-interface-auger-and-electron-surface-optical-phonon-interaction-processes-in-monolayer-graphene-deposited-on-polar-substrates-von-mounira-mahdouani-bourguiga","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
