Summary: In this study, we present new findings on the fundamental physicochemical properties of GeS and GeSe in bulk form. The experimental results obtained using UV and X-ray photoelectron spectroscopies provide reliable values of the work functions, electron affinities and ionization energies, as well as core level lines. The band gaps of the materials were determined by photoreflectance and optical absorption methods, and band energy diagrams relative to the vacuum level were constructed. These diagrams are crucial for the design of various electronic devices and semiconducting heterostructures.

Summary: With a fully first-principles modelling approach, this study predicts the thermoelectric properties of different phases of GeS and GeSe. It finds that n-doped Pnma GeSe has a high thermoelectric figure of merit ZT, which can be a good match for p-type SnSe in a thermoelectric couple. It also suggests that p-doped R3m GeS and GeSe can achieve an industrially-viable ZT, and alloying can further improve the performance.

Summary: Newly emerged 2D material Bi2O2Se has attracted significant attention for its unique band structure and ultrafast optical properties. However, the performance of Bi2O2Se-based photodetectors is limited due to contact issues and high Schottky barrier caused by fabrication contaminants and work function mismatch. In this work, efficient photodetection is achieved by utilizing an all-Bi2O2Se device geometry with tailored Schottky barrier. The photodetector exhibits strong photoresponse to visible and near-infrared light, achieving high photoresponsivity and specific detectivity.

Summary: Two-dimensional van der Waals heterostructures (2D vdWHs) have attracted widespread attention for their abundant and exotic properties, offering new possibilities for next-generation nanoelectronics. However, the lack of high-throughput fabrication techniques poses challenges for practical applications. In this study, a general electrochemical strategy is demonstrated to prepare high-quality vdWHs with electrostatic forces driving the stacking of individual assemblies, resulting in strong interlayer interactions. Thin-film photodetectors based on graphene/In2Se3 vdWHs show great promise for near-infrared photodetection, with high responsivity, fast rise and decay times. This approach enables the exploration of emerging electronic, photonic, and quantum phenomena.

Summary: Atomically thin 2D transition metal dichalcogenides (TMDs) have gained attention for next-generation electronic and photoelectric device applications. Zero-dimensional quantum dots (QDs) have tunable bandgap abilities, but their low carrier mobility and surface trap states limit their use in devices. Combining 0D and 2D materials in hybrid structures offers complementary advantages and enables their application in optoelectronic devices. This article highlights recent discoveries and discusses research trends and challenges in electronic and optoelectronic devices based on hybrid heterogeneous materials.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
