A Revolutionary Discovery from Denmark!

Researchers at Aarhus University have made a groundbreaking discovery that could reshape our understanding of materials—introducing AgGaGe3Se8, a crystalline material that conducts heat worse than both glass and water!

This seemingly paradoxical finding has revealed that, despite its crystalline structure, AgGaGe3Se8 behaves more like glass when it comes to transporting heat. With a thermal conductivity of just 0.2 watts per meter-Kelvin at room temperature, it’s three times less effective than water and five times less than standard silica glass.

What’s Inside This Unique Material?

AgGaGe3Se8 is a fascinating cocktail of elements—silver (Ag), gallium (Ga), germanium (Ge), and selenium (Se)—known for its optical properties. However, it’s the thermal transport properties that have captured researchers' attention for the first time.
