Cross-interface model for the thermal transport across interface between overlapped nanoribbons

Abstract

The application of low-dimensional materials for heat dissipation requires a comprehensive understanding of the thermal transport at the cross-interface, which widely exists in various composite materials and electronic devices. In this work, an analytical model is proposed, named as cross-interface model (CIM), to accurately reveal the essential mechanism of the two-dimensional thermal transport at the cross-interface. The applicability of CIM is validated through the comparison of the analytical results with molecular dynamics simulations for a typical cross-interface of two overlapped boron nitride nanoribbons. Besides, it is figured out that the factor η has important influence on the thermal transport besides the thermal resistance inside and between the materials, which is found to be determined by two dimensionless parameters from its expression. The investigations would deepen the understanding of the thermal transport at the cross-interface and also facilitate to guide the applications of low-dimensional materials in thermal management.
