The Best Way to Thermalize Electrons

Tuesday March 9th 2021

In our new application note, QDevil presents a detailed procedure for quantifying the temperature of the electrons in milli-Kelvin experiments.

This application note provides all the specifics on Coulomb blockade electron thermometry in a quantum dot device. In addition, it outlines the best practice for thermalizing electrons in a dilution refrigerator, particularly by using the QFilter-II. The note also highlights further noise reducing practices utilizing other QDevil products. We discuss the details of the setup and the analysis of a featured experiment in which an electron temperature of 28 mK is reached with a measured phonon temperature of 18 mK in the dilution refrigerator.
