Cryothermal Measurements of Variable-Emittance Coatings with Lower Phase Transition Temperatures for Space Thermal Control
Chloe Stoops, Vishwa Krishna Rajan, Liping Wang
Space thermal control is critically important to ensure proper operation of on-board equipment in a regulated temperature range. Passive thermal control with variable-emittance coa…
Tunable Coatings on Various Substrates for Self-Adaptive Energy Harvesting with Daytime Solar Heating and Nighttime Radiative Cooling
Ken Araki, Vishwa Krishna Rajan, Liping Wang
In this work, tunable vanadium dioxide (VO2) metafilms on different substrate materials fabricated via low-oxygen furnace oxidation are demonstrated for self-adaptive daytime solar…
High-quality Tungsten-doped Vanadium Dioxide Thin Films Fabricated in an Extremely Low-oxygen Furnace Environment
Vishwa Krishna Rajan, Ken Araki, Robert Y. Wang +1
This work reports the fabrication and characterization of high-quality tungsten-doped vanadium dioxide (WxV1-xO2, x = 0~3 at. %) by thermal oxidation of sputtered tungsten-vanadium…
Maximizing Infrared Transmission Contrast Upon Phase Transition of Thermally Grown Vanadium Dioxide Thin Films by Rapid Thermal Processing
Ken Araki, Vishwa Krishna Rajan, Liping Wang
Pristine vanadium dioxide (VO2), an insulator-to-metal transition (IMT) material, is grown via furnace oxidation followed by rapid thermal annealing with forming gas (5%H2/95%N2) w…
Lowering Insulator-to-Metal Transition Temperature of Vanadium Dioxide Thin Films via Co-Sputtering, Furnace Oxidation and Thermal Annealing
Vishwa Krishna Rajan, Jeremy Chao, Sydney Taylor +1
Thermochromic vanadium dioxide thin films have attracted much attention recently for constructing variable-emittance coatings upon its insulator-metal phase transition for dynamic…
