Abstract

We investigate the thermal transport of the graphene/ferroelectric crystal lithium niobate (LiNbO₃) interface by molecular dynamics simulations. The results show that lithium niobate thickness are not significantly correlated with ITR, the increase of graphene area will slightly enhance ITR, and the enhancement of interfacial coupling strength leads to monotonic decrease of ITR. The increasing ambient temperature and graphene vacancy concentration promote the vibration of low-frequency phonons in graphene and lithium niobate, resulting in a gradual decrease in the ITR of the interface. In addition, low concentration hydrogenation on both sides of monolayer graphene can also effectively reduce ITR and improve the heat transfer performance between interfaces. This study contributes to understand the thermal transport of the graphene/LiNbO₃ interfaces and provides an effective method for efficient thermal management of graphene/LiNbO₃ interfaces in optoelectronic devices.

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
