“Heat death”, namely, overheating, which will deteriorate the function of chips and eventually burn device has become an obstacle in roadmap semiconductor industry. Therefore, heat dissipation becomes a key issue further developing semiconductor. Heat conduction encompasses intricate dynamics phonon within one-dimensional, two-dimensional materials, as well transport through interfaces. In this paper, research progress complexities on nano nanoscale recent three years, especially size dependent thermal relationship between anomalous diffusion are summarized. Further discussed paper is fundamental question non-equilibrium statistical physics, particularly necessary sufficient condition for given Hamiltonian whose macroscopic behavior obeys Fourier’s law. On other hand, methods engineering conduction, encompassing nanophononic crystals, nanometamaterials, interfacial phenomena, condensation also introduced. order to comprehensively understand phononic succinct overview spanning from quantization Hall effect chiral phonons their interactions with carriers presented. Finally, challenges opportunities, potential application quantum information discussed.
