  4. 7. Interaction between electronic and vibrational edge states in graphene

    Author : Anton Vikström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; collective excitations; quantum acous- tics; quantum Hall effect; edge waves; graphene; solitons;

    Abstract : A sheet of graphene in a magnetic field perpendicular to the sheet has electronic edge states with nonzero velocities. These edge states are localized to the edge of the sheet on the order of the magnetic length. READ MORE

  5. 8. Excitation and Excited State Properties of Heterocyclic Chromophores. Indole and Purine Derivatives of Biological Significance

    Author : Bo Albinsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear dichroism LD ; fluorescence polarization anisotropy FPA ; electronic excitations; magnetic circular dichroism;

    Abstract : Proteins and nucleic acids absorb light in the near-UV due to the presence of aromatic heterocyclic chromophores. In this work linear dichroism (LD) in combination with fluorescence polarization anisotropy (FPA) and magnetic circular dichroism (MCD) is used to investigate electronic excitations and excited states of indole derivatives, purine derivatives, the wye base, 2-phenylindole and 4',6-diamidino-2-phenylindole (DAPI).

  6. 9. Heavy-Core Staffanes : A Computational Study of Their Fundamental Properties of Interest for Molecular Electronics

    Author : Niclas Sandström; Henrik Ottosson; Leif Hammarström; Bo Albinsson; Uppsala universitet; []
    Keywords : Organic chemistry; conjugation; polarizability; Group 14 elements; cage compounds; electronic excitations; quantum chemistry; molecular electronics; Organisk kemi;

    Abstract : The basic building blocks in molecular electronics often correspond to conjugated molecules. A compound class consisting of rigid rod-like staffane molecules with the heavier Group 14 elements Si, Ge, Sn and Pb at their bridgehead positions has now been investigated. READ MORE
