Abstract
The thermal transport property in low-dimensional structures has been studied theoretically taking into account the effect of temperature on phonon–phonon coupling. New thermal-transport equations are developed to discriminatively treat the ballistic and diffusive thermal transport in quantum structures. Using the new thermal transport equations, the thermal transport properties in GaAs nanowire and zigzag graphene nanoribbon are investigated to demonstrate the crossover from ballistic to diffusive thermal transport.
