Conductivity of graphene: How to distinguish between samples with short- and long-range scatterers

Applying a quasiclassical equation to carriers in graphene, we found a way how to distinguish between samples with the domination of short- and long-range scatterers from the conductivity measurements. The model proposed explains recent transport experiments with chemically doped as well as suspended graphene. Copyright (c) EPLA, 2008.
