Terahertz nanospectroscopy of plasmon polaritons for the evaluation of doping in quantum devices

Terahertz (THz) waves are a highly sensitive probe of free carrier concentrations in semiconducting materials. However, most experiments operate in the far-field, which precludes the observation of nanoscale features that affect the material response. Here, we demonstrate the use of nanoscale THz pl...
