Cascaded superconducting junction refrigerators: Optimization and performance limits [PDF]
Applied Physics Letters, 2021 We demonstrate highly transparent silicon–vanadium and silicon–aluminum tunnel junctions with relatively low sub-gap leakage current and discuss how a trade-off typically encountered between transparency and leakage affects their refrigeration performance.

Performance comparison of the single-refrigerant cascade refrigerating system
Energy Reports, 2022 In the food refrigeration industry, the single-stage compression refrigerating system cannot meet the operating conditions of a high-pressure ratio when the evaporating temperature decreases. The cascade refrigerating system (CRS) is an alternative technical solution to solving the mentioned problem.
