1. Strain-induced nonlinear Hall effect in graphene systems
University essay from Stockholms universitet/FysikumAbstract : This thesis aims to study the nonlinear electrical transport response of monolayer and bilayer graphene systems under the influence of different lattice deformations (strain). Broken inversion and rotation symmetries can generate a second-order transverse current response called the nonlinear Hall effect in the presence of time-reversal symmetry. READ MORE

2. Evaulation of liquid-exfoliatedgraphene as additive in Ag-basedsliding contacts
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : This master thesis work is performed at ABB Corporate Research Center inVästerås. The aim of this study is to investigate Ag:graphene composites as slidingelectrical contacts, suitable for use in e.g. tap-changers. READ MORE

3. Electrochemical functionalization of epitaxial graphene
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : In this work graphene has been functionalized with antibodies. Different functionalization methods of graphene already found in literature have been evaluated. An electrochemical functionalization process with subsequent immobilization of antibodies have been chosen for this thesis. READ MORE

4. Multi-wavelength Raman characterization of back-gated monolayer and bilayer graphene
University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)Abstract : In this work, we investigate the Raman spectrum of gated monolayer and bilayergraphene devices. We used Raman spectroscopy with three different excitationwavelengths: (488nm, 514nm and 633nm).For monolayer devices we observedthe expected behavior for doped devices. READ MORE
