Phonon Conduction in Silicon Nanobeam Labyrinths

Scientific Reports, 2017
AbstractHere we study single-crystalline silicon nanobeams having 470 nm width and 80 nm thickness cross section, where we produce tortuous thermal paths (i.e. labyrinths) by introducing slits to control the impact of the unobstructed “line-of-sight” (LOS) between the heat source and heat sink.
