Summary: Graphene/BN heterostructures exhibit significant thermal rectification behavior, and the rectification ratio increases with the system length. This phenomenon is attributed to the mismatch of out-of-plane phonon vibration modes at the interface. This two-dimensional heterostructure shows promise for thermal management.

Summary: This study explores the influence of interlayer rotation angle theta on interfacial thermal transport across graphene/h-BN heterostructure using molecular dynamics simulation. The thermal conductance at the interface decreases with increasing rotation angle, mainly due to the reduction in low-frequency phonon contribution. Rotation enhances surface fluctuation in the graphene layer, leading to a rotation angle-dependent thermal conductance.

Summary: The discovery of 'magic angle' graphene and the use of hexagonal boron nitride as a substrate have sparked great interest in heterostructure systems. Researchers studied the band structure, density of states, and charge distribution of a twisted graphene/hexagonal boron nitride/graphene sandwich structure, and found specific evolution patterns and metal-insulator phase transition. The results have practical implications for heterojunction electronic devices.

Summary: In-plane hybrid graphene/hexagonal boron nitride (h-BN) heterostructure is studied using molecular dynamics simulation. The structural evolution and thermal dynamics of the heterostructure are investigated, revealing the first order phase transition, formation of gaseous atoms, and significant changes in coordination number at specific temperatures. The influence of the relative number of h-BN to graphene atoms on the phase transition temperature is also discussed.

Summary: Graphene on hexagonal boron nitride (h-BN) demonstrates excellent electrical properties, which are affected by its domain size and boundaries. Chemical vapor deposition (CVD) is a hopeful method for large graphene crystal growth, but increasing the coverage of monolayer graphene on h-BN remains a challenge due to weak control of nucleation and vertical growth. In this study, an auxiliary source strategy using silicon carbide and methyl methacrylate is adopted to enhance graphene nucleation density and achieve continuous graphene films on h-BN. By optimizing the growth temperature, vertical accumulation of graphitic materials can be suppressed. This work provides an effective approach for preparing continuous graphene film on h-BN and offers insights for the growth of high-quality graphene.

Summary: In this study, h-BN particles were utilized as a dopant on the surface of CNTs to form a heterostructure. The successful synthesis of the h-BN/CNT nanostructure was confirmed through FT-IR and Raman spectra. Scanning electron microscopy was used to study the morphology and microstructure of the achieved heterostructure. The doping of h-BN enhanced the hydrogen adsorption capacity of CNTs, leading to an increased active sites for hydrogen adsorption and a maximum specific capacity of 1150 mA h/g.

Summary: This study proposes a growth process mediated by an hBN/G interface for the controlled synthesis of high-quality monolayer hBN. The scalable epitaxy of unidirectional monolayer hBN on graphene aligned to the underlying graphene lattice is achieved. Additionally, it is discovered that monolayer hBN exhibits deep-ultraviolet emission with a giant renormalized direct bandgap on graphene.
