We discuss the realization of vertical heterostructures consisting of two-dimensional materials, such as graphene and transition metal dichalcogenides, using a layer-by-layer transfer approach. We demonstrate double layer heterostructures consisting of two graphene layers separated by a thin hexagonal boron nitride dielectric, with layer mobilities as high as 200,000 cm2/Vs. We discuss the in-plane electron transport as a function of temperature and in magnetic fields, as well as the tunneling between the two layers, which can be used as basis for vertical field-effect transistors.
