Microkelvin electronics on a pulse-tube cryostat with a gate Coulomb-blockade thermometer

Mohammad Samani et al.

Summary: This paper introduces a rigidly wired metallic sample holder that solves the problem of pulse-tube vibrations and demonstrates an improved type of temperature sensor. It provides a microkelvin environment with low heat leaks and extends the temperature measurement range to as low as 160 mu K. The research also gives an outlook for cooling below 50 mu K for future microkelvin transport experiments.

Coulomb Blockade Thermometry Beyond the Universal Regime

Nikolai Yurttagul et al.

Summary: The study shows that even when considering variations in device parameters, the conductance characteristics of the primary regime can be extended for large arrays. The simulations agree well with measured conductance traces in the submillikelvin electron temperature regime.
