| Sumario: | Managing heat dissipation in nanoscale electronic devices and understanding the underlying mechanisms complicated due to the reduced scale at the interface between the various materials. Here, the authors detect an extremely small interface thermal resistance is in amorphous-(a-) GeS/epitaxial-(e-) PbTe superlattice and perform calculations showing that heat conduction in nanoscale systems with high density interfaces might be controlled by phonon density of states and group velocity similarities. |
