Gauging electronic transport in Sodium Iridate and Vanadium Triiodide thin crystals through graphene heterostructures*

Sodium Iridate (Na₂IrO₃) presents exciting ground states thanks to the combination of electronic correlations, spin-orbit coupling, crystal field effects and a honeycomb arrangement of the iridium ions. Vandium triiodide (VI₃) on the other hand, constitutes a promising candidate for 2-D magnetism. Due to the highly insulating behavior of these materials, little progress has been made in terms of transport measurements. Here we explore an indirect transport measurement of thin exfoliated Na₂IrO₃ and VI₃ crystals through a graphene heterostructure.
