Carrier Transport in Two-Dimensional Graphene Layers

Carrier transport in gated 2D graphene monolayers is considered in the presence of scattering by random charged impurity centers with density n(i). Excellent quantitative agreem...

Transport in chemically doped graphene in the presence of adsorbed molecules

Motivated by a recent experiment reporting on the possible application of graphene as sensors, we calculate transport properties of 2D graphene monolayers in the presence of ads...

Experimental manifestation of topological lifshitz transition by observing thickness-dependent shift of plasma frequency in topological semimetals

Measurement of Scattering Rate and Minimum Conductivity in Graphene

The conductivity of graphene samples with various levels of disorder is investigated for a set of specimens with mobility in the range of 1-20x10(3) cm2/V sec. Comparing the exp...
