Summary: The investigation of lattice thermal conductivity in few-layer black phosphorus reveals an anisotropic thermal conductivity cross-over between zigzag and armchair directions at low temperatures. The study addresses the transition regimes of anisotropic-isotropic-low anisotropic thermal conductivity in black phosphorus and discusses the influence of phonon-boundary, phonon-phonon, and phonon-impurity scattering. The obtained phonon scattering coefficients are used to describe the thermal conductivity cross-over of zigzag and armchair black phosphorus, showing a good fit to experimental reports in a wide temperature range.

Summary: Theoretical investigations on the lattice thermal conductivity of zigzag and armchair black phosphorus have been conducted, with the significant impact of normal phonons on scattering rates explored at different temperatures. The transition towards higher frequencies in the zigzag and armchair directions due to normal phonons at lower temperatures was observed, along with the considerable contributions of normal phonons in higher dimension samples affecting thermal conductivity. The results were compared with recent experimental data, showing a significant reduction in thermal conductivity caused by normal phonons.

Summary: The study investigates the anisotropic characteristics of black phosphorus crystal through the Raman tensor and birefringence, revealing the typical linear dichroism in the generation and detection of coherent phonons. The detection process is influenced by anisotropic multiple thin film interference, while A(g)(1) and A(g)(2) optical phonons decay into lower frequency acoustic phonons through a temperature-dependent anharmonic process.

Summary: This study investigates the dynamic behavior and thermoelastic damping of a circular single-layer black phosphorus-based (CSLBP-based) mass sensor. Molecular dynamic simulations and a circular orthotropic elastic plate model are used to analyze the natural frequency of CSLBP attached atomic mass. It is found that the natural frequency of the mass sensor is highly sensitive to the attachment mass, while the thermoelastic damping depends on the radius of the sensor, attachment mass, and environmental temperature. The circular orthotropic elastic plate model can effectively predict the dynamic behavior of the CSLBP-based mass sensor.

Summary: Exciting out-of-plane acoustic phonon (ZA) in black phosphorene (BP) can strongly modulate its carrier mobility and band gap, with a 1% tensile strain significantly enhancing the ZA mode excitation, reducing the band gap and carrier mobility. This unique control over electronic properties of BP provides valuable guidelines for designing functional nanodevices based on 2D BP.

Summary: Molecularly confined polymer fillers in nanopores were found to enhance the thermal conductivity of polymer nanocomposites by providing superior mechanical properties. This enhancement is attributed to the better aligned and less entangled chains in the confined phase, resulting in reduced chain-chain phonon scatterings. This work offers essential insights for multifunctional thermal and mechanical applications of polymer nanocomposites.

Summary: Thermal percolation, the rapid increase in thermal transport in polymer nanocomposites, is of great interest in thermal management. However, it remains a challenging subject in both experimental and modeling aspects. Previous studies on thermal percolation have mainly focused on high-aspect-ratio, conductive fillers. This study demonstrates that thermal percolation can be achieved even with nonconductive spherical fillers at a low volume fraction. Additionally, the effects of volume fraction, interfacial thermal resistance, and filler conductivity on thermal conductivity are found to deviate from effective medium approximations.
