A New Heat Transport Regime Discovered in Ultrathin Semiconductors
AI-summarised brief · reviewed before publication
Researchers have discovered a new heat transport regime in ultrathin semiconductors, specifically in molybdenum disulfide and molybdenum diselenide. This regime, known as hydro-thermoelastic transport, exhibits highly impeded thermal diffusion. The study, published in Nature Physics, reveals complex effects such as phonon hydrodynamics and mechanical deformations that affect heat movement. Using an advanced optothermal technique, the team observed heat propagating much more slowly than predicted. This discovery challenges conventional understanding of diffusive heat transport and could impact thermal management in devices. The findings provide new insight into nanoscale heat transport and could enable designing devices with new functionalities.
