  1. 1. Strain-induced nonlinear Hall effect in graphene systems

    University essay from Stockholms universitet/Fysikum

    Author : Pedram Pakmehr; [2022]
    Keywords : ;

    Abstract : 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

  4. 3. Electrochemical functionalization of epitaxial graphene

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Petter Lindgren; [2015]
    Keywords : Technology and Engineering;

    Abstract : 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

  5. 4. Multi-wavelength Raman characterization of back-gated monolayer and bilayer graphene

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Maedeh Arvani; Mahdi Aghajanloo; [2012]
    Keywords : ;

    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
