Charge localization increases chemical expansion in cerium-based oxides
(2012)In this work, we demonstrate the mechanism by which electronic charge localization increases the chemical expansion coefficient in two model systems, CeO 2-? and BaCeO 3-?. Using Density Functional Theory calculations, we ... -
Ion irradiation induced structural and electrical transition in graphene
(2010)The relationship between the electrical properties and structure evolution of single layer graphene was studied by gradually introducing the gallium ion irradiation. Raman spectrums show a structural transition from ...
