## Description

- description: We report on observation of the far-infrared photoresistance of twisted
    bilayer graphene (tBLG) under continuous quantum cascade laser illumination at
    a frequency of 57.1 THz. The photoresis- tance shows an intricate sign-alternating
    behavior under variations of temperature and back gate voltage, and exhibits giant
    resonance-like enhancements at certain gate voltages. The structure of the photoresponse
    correlates with weaker features in the dark dc resistance reflecting the complex
    band structure of tBLG. It is shown that the observed photoresistance is well
    captured by a bolomet- ric model describing the electron and hole gas heating,
    which implies an ultrafast thermalization of the photoexcited electron-hole pairs
    in the whole range of studied temperatures and back gate volt- ages. We thus establish
    that photoresistance can serve a highly sensitive probe of the temperature variations
    of electronic transport in tBLG.
