Nano-Engineered Thin-Film Thermoelectric Materials Enable Practical Solid-State Refrigeration

Nano-engineered thin-film thermoelectric materials enable practical solid-state refrigeration

Refrigeration needs are increasing worldwide with a demand for alternates to bulky poorly scalable vapor compression systems. Here, we demonstrate the first proof of practical solid-state refrigeration, using nano-engineered controlled hierarchically engineered superlattice thin-film thermoelectric materials. With 100%-better thermoelectric materials figure of merit, ZT, than the conventional bulk materials near 300 K, we demonstrate (i) module-…

US Scientists, Samsung Team Hit 100% Cooling Efficiency With No Refrigerants

Refrigerators and air conditioners have become necessities in modern life, but the technology driving them hasn’t changed much in decades until now. In a groundbreaking collaboration, Samsung and researchers at the Johns Hopkins Applied Physics Laboratory (APL) are turning the page on traditional cooling methods by developing solid-state, thermoelectric-based refrigeration that could render compressor-based systems […] The post US Scientists, Sa…

Revolution in Cold: Nanotechnology Replaces Compressors - Economic Scenarios

It can be cooled, and much more efficiently, with a system that does not use noisy compressors, but simply by passing electricity through a nanocell. Researchers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have developed a new, easily fabricated solid-state thermoelectric refrigeration technology using nanoengineered materials that is twice as efficient as devices made with commercially available thermoelectric mat…

Thin film thermoelectric cooling built with semiconductor process technology

Researchers at the Johns Hopkins Applied Physics Laboratory (APL) and Samsung Electronics have developed a solid state thermoelectric cooling material that can be built in volume with semiconductor process technology. The controlled hierarchically engineered superlattice structures (CHESS) are twice as efficient as devices made with commercially available bulk thermoelectric materials for cooling electronic equipment. The CHESS […] The post Thin…
