Summary: This research investigates the emergence of special corner modes in elastic twisted kagome lattices, which are localized at specific corners independent of the overall shape. The existence of these modes is attributed to charge accumulation at the boundary, confirmed by the charge distribution plot in a finite lattice.

Summary: The study aims to investigate the impact of bulk vibrational properties and interfacial structure on thermal transport at interfaces in wide band gap semiconductor systems. The results suggest that thermal conductance depends on the bulk phonon properties of the softer material and the interfacial structure, rather than just the vibrational similarity between the two materials.

Summary: Excitonic insulators exhibit collective many-body effects, but lack evidence of long-range coherence and the origin of the ordered phase in these systems is controversial. By studying Ta2NiSe5, anomalous micrometer-scale propagation of coherent modes was observed, attributed to the hybridization between phonon modes and the condensate's phase mode. Electronic interactions play a substantial role in the ordered phase of Ta2NiSe5.

Summary: In this article, the static and dynamic characterizations of semiconductors with different materials at room temperature and cryogenic temperature are evaluated and compared. The results show that silicon and gallium nitride-based semiconductors have improved performances at low temperature, while silicon carbide-based semiconductors exhibit reduced performance. These evaluation results can guide cryogenic power electronics applications and future semiconductor characterization research.

Summary: We used IR-sSNOM to investigate SPPs in TLG and found systematic differences in near-field IR spectra and SPP wavelengths between Bernal (ABA) and rhombohedral (ABC) TLG domains on SiO2, which can be explained by stacking-dependent intraband conductivities. The reflection profiles of SPP at ABA-ABC boundaries can be largely explained by an idealized domain boundary defined by conductivity discontinuity. However, we observed distinct shapes in the SPP profiles at the edges of ABA and ABC TLG, which cannot be solely attributed to idealized edges with stacking-dependent conductivities. Instead, this can be explained by the presence of various edge structures with local conductivities differing from bulk TLGs.

Summary: Recent discoveries of materials with ultralow thermal conductivity provide a pathway for significant developments in thermoelectricity. A comparative study of three chemically similar antimonides reveals the root causes behind their extraordinarily low thermal conductivity. The study shows that localized phonon modes with unusually low frequencies and framework bonding contribute to the suppression of thermal conductivity. Understanding thermal transport in structurally complex materials is crucial for the development of the next generation of thermoelectrics.

Summary: The emergence of wide and ultrawide bandgap semiconductors has revolutionized the advancement of next-generation power, RF, and optoelectronics, but the thermal boundary resistance at semiconductor interfaces hinders heat dissipation. Many new high thermal conductivity materials and techniques have been developed to improve thermal boundary resistance, and simulation methods have been developed to advance understanding. However, there is a large gap between experiments and simulations. This review comprehensively summarizes the experimental and simulation works, aiming to build a structure-property relationship between thermal boundary resistance and interfacial nanostructures and to improve thermal boundary resistance.
