Transport in Bilayer Graphene at the Charge Neutrality Point

ORAL

Abstract

Bilayer graphene (BLG) at the charge neutrality point is strongly susceptible to electronic interactions, and expected to undergo a phase transition into a state with spontaneous broken symmetries. We experimentally investigate transport properties of a large number ultra-clean BLG devices as functions of temperature, disorder, out-of-plane electric field, and charge density. We will discuss the results in terms of various theoretical models and possible phase transitions ~arising from the rich many body physics in this 2D system.
