Fabrication of a PtTe_2 / α-RuCl₃ van-der-Waals Heterostructure for Electronic Transport 

PtTe₂ is an air-stable exfoliatable Dirac semimetal that features a type-II Dirac cone. In that cone, electrons follow a linear dispersion relation that is anisotropic along the z axis of momentum. The type-II Dirac Cone of PtTe₂ is 1 eV below the Fermi energy, which makes it hard to access through electronic transport experiments that involve PtTe₂ alone. α-RuCl₃ is a material that is known to be a very good electron acceptor. We construct a PtTe₂ and α-RuCl₃ heterostructure to hole dope PtTe₂ and potentially observe signatures of the type-II fermions under electronic transport. We discuss the methods involved in creating this heterostructure, how we isolate thin flakes of PtTe₂, and preliminary results on transport of a PtTe₂ / α-RuCl₃ heterostructure.
