As a 2D material with distinctive ferroelectric properties, InSe offers significant potential for the applications in information memory and advanced data storage technologies. It also exhibits a complex phase diagram that is highly sensitive to temperature and pressure variations, resulting in diverse lattice configurations. While extensive studies have focused on the phase transition behavior of InSe, its impact on phonon transport remains largely unexplored.

Surface-enhanced Raman spectroscopy (SERS) by 2D semiconductors relies on chemical (CM) enhancement driven by charge-transfer (CT) processes in bandgap alignment between molecules and substrates. Unfortunately, the low light absorption and weak conferment in the atomic-layer material limit the enhancement factor of Raman intensity (EFRI). Improving the utilization efficiency of excitation light is therefore essential for promoting SERS performance of 2D semiconductors.

The emergence of two-dimensional (2D) materials, particularly in the form of nanosheets, has attracted significant attention due to their extraordinary properties that differ markedly from those of their bulk counterparts. Among these materials, zinc oxide (ZnO) stands out for its highly tunable electronic, optical, and mechanical properties. However, understanding strain-induced phase transitions in few-layer systems remains a critical challenge, especially in nanoporous ZnO architectures.

High-power electronics demand high-speed, highly integrated electrical circuits with excellent heat dissipation. Owing to their ultrawide-bandgap, high thermal stability and chemical inertness, the heterostructure of cubic boron nitride (c-BN) and diamond are predicted as promising power-efficient materials for next-generation electronics. Therefore, extensive efforts are ongoing to develop epitaxial c-BN thin films on diamond with an atomically smooth interface, however with limited success due to the metastable nature of c-BN.

Cathodic exfoliation of graphite has emerged as an attractive method to synthesize high-quality and lo- defect graphene. Here, it is demonstrated that the type of starting graphite material influences the properties of exfoliated graphene. Graphite foil, natural graphite, and graphite rods were examined in the exfoliation processes performed in 3.
