Graphene on SrTiO3
S. Das Sarma, Qiuzi Li
We study carrier transport through graphene on SrTiO substrates by considering relative contributions of Coulomb and resonant impurity scattering to graphene resistivity. We es…
Temperature-dependent compressibility in graphene and two-dimensional systems
Qiuzi Li, E. H. Hwang, S. Das Sarma
We calculate the finite temperature compressibility for two-dimensional semiconductor systems, monolayer graphene, and bilayer graphene within the Hartree-Fock approximation. We fi…
Disorder by order in graphene
S. Das Sarma, E. H. Hwang, Qiuzi Li
We predict the existence of an intriguing "disorder by order" phenomenon in graphene transport where higher quality (and thus more ordered) samples, while having higher mobility at…
Disorder-induced temperature-dependent transport in graphene: Puddles, impurities, activation, and diffusion
Qiuzi Li, E. H. Hwang, S. Das Sarma
We theoretically study the transport properties of both monolayer and bilayer graphene in the presence of electron-hole puddles induced by charged impurities which are invariably p…
Theory of 2D transport in graphene for correlated disorder
Qiuzi Li, E. H. Hwang, E. Rossi +1
We theoretically revisit graphene transport properties as a function of carrier density, taking into account possible correlations in the spatial distribution of the Coulomb impuri…
