Intrinsic plasmons in 2D Dirac materials
S. Das Sarma, Qiuzi Li
We consider theoretically, using the random phase approximation (RPA), low-energy intrinsic plasmons for two-dimensional (2D) systems obeying Dirac-like linear chiral dispersion wi…
Two-dimensional metal-insulator-transition as a potential fluctuation driven semiclassical transport phenomenon
S. Das Sarma, E. H. Hwang, Qiuzi Li
We theoretically consider the carrier density tuned (apparent) two-dimensional (2D) metal-insulator-transition (MIT) in semiconductor heterostructure-based 2D carrier systems as ar…
Many-body effects and possible superconductivity in the 2D metallic surface states of 3D topological insulators
S. Das Sarma, Qiuzi Li
We theoretically consider temperature and density-dependent electron-phonon interaction induced many-body effects in the two-dimensional (2D) metallic carriers confined on the surf…
Two-dimensional electronic transport on the surface of 3D topological insulators
Qiuzi Li, E. Rossi, S. Das Sarma
We present a theoretical approach to describe the 2D transport properties of the surfaces of three dimensional topological insulators (3DTIs) including disorder and phonon scatteri…
Finite temperature inelastic mean free path and quasiparticle lifetime in graphene
Qiuzi Li, S. Das Sarma
We adopt the GW approximation and random phase approximation to study finite temperature effects on the inelastic mean free path and quasiparticle lifetime by directly calculating…
Intrinsic Electron-Phonon Resistivity in Bi2Se3 in the Topological Regime
Dohun Kim, Qiuzi Li, Paul Syers +4
We measure the temperature-dependent carrier density and resistivity of the topological surface state of thin exfoliated Bi2Se3 in the absence of bulk conduction. When the gate-tun…
