文摘
- •
We model interfacial thermal resistance with nonequilibrium Green's function method.
- •
We demonstrate interfacial thermal resistance can be modulated in a large scope.
- •
A compressive pressure of 10 GPa can reduce the resistance by about 4 times.
- •
The cross-plane pressure is effective in modulating the interfacial resistance.
