A Finite-Size Study on Samarium-Substituted Bismuth Ferrite: Multiferroic and Lead-Free Piezoelectric Materials
(Master thesis, 2011)Multiferroic materials combine two or more ferroic orders such as ferroelectricity, ferromagnetism and ferroelasticity. They have a great interest for the development of the next generations of digital electronic memory ... -
A first-principles Study of epitaxial Interfaces between Graphene and GaAs
(Master thesis, 2014)Epitaxial interfaces between graphene and GaAs(111) have been investigated through a first-principles study using density functional theory (DFT). The GaAs(111) surface at the interface is assumed to be 2x2 reconstructed ... -
A Method for Controlled Oxide and Carbon Coating of Silicon Nanoparticles as Anode in Lithium-Ion Batteries
(Master thesis, 2017)Silicon has emerged as a promising alternative to graphite in lithium-ion batteries. Silicon can, theoretically, provide up to ten times higher capacity due to its high alloying capabilities with lithium. This improvement ... -
A method for describing systems of spherical droplets in vapor
(Master thesis, 2021)Det har lenge vært kjent at nanomaterialer har unike egenskaper som ikke observeres i materialer på større skala. Den unike oppførselen gjør også at nanosystemer ikke kan beskrives av de vanlige termodynamiske likningene, ... -
A new material for oxygen-permeable membranes
(Master thesis, 2017)In this study, hexagonal YMnO3 doped with 15% Ti was used in the preparation of an asymmetric oxygen permeable membrane. Several different methods for the fabrication of the asymmetric membrane have been used, and the ... -
