The nanoscale regime of materials has been at the forefront of research and interest in condensed matter physics for many years. In a merger of the fields of two-dimensional (2D) materials and high pressure physics, we present an investigation of the electronic response of carbon-based, van der Waals (vdW) heterostructures in a diamond anvil cell (DAC). Combining these fields presents us with the ability to study the characteristics of such systems both optically, and through electrical transport. Properties such as conductance, band structure, and layer number are considered. The samples in this study are assembled using exfoliation and stacking techniques adapted from the 2D materials community such that atomically thin field-effect transistors can be transferred directly onto a diamond anvil surface. We discuss various techniques and tools employed to perform photolithography and electron beam deposition on the surface of diamond to make electrical connections to the heterostructures. As a benchmark, we present pressure measurements of MnS2 using photolithographically patterned electrodes. We then present electrical measurements of graphite-gated bilayer graphene at ambient pressure and discuss avenues for future developments. We anticipate these results will lead to an entirely new platform for the investigation of high-quality heterostructures at extreme pressures.
