Graphene phononic crystals fabricated with electron-beam lithography
Lankinen, Aaro (2021)Koska grafeeni on aito kaksiulotteinen materiaali, sen avulla voidaan tutkia käytännössä teorioiden ennustamaa käyttäytymistä sellaisissa järjestelmissä. Yksi erityisen kiinnostava ilmiö on lämmönjohtavuuden lasku kun ... -
Graphene plasmons in optically forged structures
Akkanen, Suvi-Tuuli (2019)Grafeenin plasmoneiden aikaansaamiseksi täytyy jollakin tavoin poistaa virittävän valon fotonien liikemäärän ja grafeenin plasmoneiden aaltovektorin liikemäärän välinen suuri ero. Tämän tutkielman tarkoituksena oli saada ... -
Shaping graphene with optical forging : from a single blister to complex 3D structures
Mentel, Kamila K.; Manninen, Jyrki; Hiltunen, Vesa-Matti; Myllyperkiö, Pasi; Johansson, Andreas; Pettersson, Mika (Royal Society of Chemistry (RSC), 2021)Properties of graphene, such as electrical conduction and rigidity can be tuned by introducing local strain or defects into its lattice. We used optical forging, a direct laser writing method, under an inert gas atmosphere, ... -
Preparation of graphene nanocomposites from aqueous silver nitrate using graphene oxide’s peroxidase-like and carbocatalytic properties
Garg, Kunal; Papponen, Petri; Johansson, Andreas; Puttaraksa, Nitipon; Gilbert, Leona (Nature Publishing Group, 2020)The present study evaluates the role of graphene oxide’s (GO’s) peroxidase-like and inherent/carbocatalytic properties in oxidising silver nitrate (AgNO3) to create graphene nanocomposites with silver nanoparticles (GO/Ag ... -
Graphene plasmonics for surface-enhanced infrared spectroscopy
Plyushch, Alexander (2020)The work, presented in this thesis, focuses on studying graphene as a signal enhancing material for spectroscopic applications. Among many outstanding characteristics of graphene, it also exhibits attractive plasmonic ...
