The temperonic crystal: a superlattice for temperature waves
Francesco Banfi (FemtoNanoOptics team), in collaboration with colleagues from Italy, published an article entitled " Temperonic crystal : a superlattice for temperature waves in graphene " in the journal Physical Review Letters.
In the frame of a collaboration involving iLM- Université Claude Bernard Lyon 1, CNR-INO and Università Cattolica, scientists proposed tailoring materials at the nanoscale to create a temperonic crystal, a meta -material acting as a superlattice for temperature waves. In their study, the authors propose, as a paradigmatic example, a structure consisting of a graphene sheet adhering on a supporting substrate whose physical properties are periodically modulated in space. The Temperonic Crystal extends the concept of superlattice to the realm of temperature and heat transfer, enabling consistent control of temperature pulses over ultra-fast time scales. This concept paves the way to a new generation of thermal nanodevices based on wave effects, such as temperature filters, waveguides and cavities.
