In this talk, I will discuss the challenges in the characterization of low dimensional materials with an electrical engineering perspective. Techniques such as photoemission and time resolved photoemission will be presented and I will illustrate with some experimental data on nanomaterials e.g., graphene or 2D analogues standalone or in heterostructures formed by the assembly of at least 2 nanomaterials for device purposes. At last, I will focus on temperature controlled thermoelectric characterization and present an instrumentation assembled for that purpose.
