Hot Carrier Thermalization and Josephson Inductance Thermometry in a Graphene-based Microwave Circuit

Posted by klaurent August 29, 2022Caltech

Kavli Affiliate: Keith C. Schwab | First 5 Authors: Raj Katti, Harpreet Arora, Olli-Pentti Saira, Kenji Watanabe, Takashi Taniguchi | Summary: Due to its exceptional electronic and thermal properties, graphene is a key material for bolometry, calorimetry, and photon detection. However, despite graphene’s relatively simple electronic structure, the physical processes responsible for the transport of […]
