Heat-pulse rectification in carbon nanotube Y junctions
Abstract
Using molecular-dynamics simulations we demonstrate the existence of heat-pulse rectification in carbon nanotube Y junctions. The heat pulse is found to propagate unimpeded from stem to branches, while in the reverse direction there is a substantial reflection back into the branches with significantly reduced transmission. Based on this we discuss the implications for phonon rectification applications for these junctions.
