Atomistic -matrix theory of disordered 2D materials: Bound states, spectral properties, quasiparticle scattering, and transport
Kristen Kaasbjerg
In this work, we present an atomistic first-principles framework for modeling the low-temperature electronic and transport properties of disordered two-dimensional (2D) materials w…
Weak localization measurements of electronic scattering rates in Li-doped epitaxial graphene
Ali Khademi, Kristen Kaasbjerg, Pinder Dosanjh +4
Early experiments on alkali-doped graphene demonstrated that the dopant adatoms modify the conductivity of graphene significantly, as extra carriers enhance conductivity while Coul…
Tunable valley Hall effect in gate-defined graphene superlattices
Johannes H. J. Martiny, Kristen Kaasbjerg, Antti-Pekka Jauho
We theoretically investigate gate-defined graphene superlattices with broken inversion symmetry as a platform for realizing tunable valley dependent transport. Our analysis is moti…
Signatures of adatom effects in the quasiparticle spectrum of Li-doped graphene
Kristen Kaasbjerg, Antti-Pekka Jauho
We study the spectral function and quasiparticle scattering in Li-decorated graphene (Li@graphene) with an atomistic -matrix formalism and uncover adatom-induced spectral effect…
Fluctuation-driven Coulomb drag in interacting quantum dot systems
Miguel A. Sierra, David Sánchez, Antti-Pekka Jauho +1
Coulomb drag between nanoscale conductors is of both fundamental and practical interest. Here, we theoretically study drag in a double quantum-dot (QD) system consisting of a biase…
