Photonic paper published in Science Advances

The wave nature of lights and sounds has been investigated for several decades, and forms the basis of numerous technological devices. Yet the wave nature of heat has been difficult to experimentally demonstrate - due the extremely short wavelength of heat vibrations (a few nanometers at room temperature). Now a team of LIMMS researchers, hosted in the phonic lab of host Pr Nomura, has just demonstrated the wave-like properties of heat propagation. Thanks to advanced expertises in nanofabrication and thermal charaterization, they showed how a sillicon membrane with a disordered array of holes conducted heat more quickly than an membrane with a periodic array array of holes. This work may open avenue to engineer heat transport at the nanoscale, for example in view of harvesting energy.
