Thermoelectric (TE) energy harvesting was first used by NASA in 1961 but has been too inefficient and expensive for widespread applications on Earth. Conventional TE materials (Bi2Te3 and PbTe) rely on rare minerals, making it difficult to reduce costs. In contrast, carbon is an abundant material, and carbon-based TEs could decrease costs and increase adoption of thermal energy scavenging technologies, particularly by taking advantage of carbon nanostructures. To optimize such TEs, it is important to understand key yet interdependent material properties, such as thermopower or Seebeck coefficient (S), their electrical (σ) and thermal conductivity (k). This work has focused on developing accurate metrologies to unravel the physics of thermal and TE transport in carbon-based nanomaterials. First, we describe the design and construction of a bulk thermal and TE measurement tool that can be used to rapidly characterize cross-plane thermal conductivity and Seebeck voltage of macroscale materials. Next, we discuss a suspended infrared microscopy-based technique that is designed to measure the in-plane thermal conductivity of suspended thin films. Finally, we describe the design and fabrication of an on-chip thermometry platform used to measure TE properties of sub-10 nm thin films. Using the metrologies designed and built in this thesis, we are able to comprehensively study nano- to macroscale materials for thermal and TE applications.
