Dataset description
We report on significant enhancements to the integration of terahertz (THz) quantum cascade lasers (QCL) and THz detection with a two-dimensional electron (2DEG) within a dilution refrigerator obtained by the inclusion of a multi-mesh 6THz low-pass filter to block IR radiation, a Winston cone to focus light output, and gating the 2DEG for optimised sensitivity. We show that these improvements allow us to obtain a >2.5 times reduced sample electron temperature (160mK compared with 430 mK previously), during cyclotron resonance (CR) measurements of a 2DEG under QCL illumination. This opens up a route to performing sub-100mK experiments using excitation by THz QCLs.
