Summary: Monolayer and bilayer lateral heterostructures based on ternary alloys of MoS2(1-x)Se2x-WS2(1-x)Se2x were successfully synthesized by modifying the ratio of the source precursors. The bandgaps of both materials in the heterostructure can be continuously tuned, and good intradomain composition homogeneity was observed. The band alignments in different heterostructures depend on the composition and can be affected by unintentional electronic doping during growth.

Summary: The fabrication of hBN-encapsulated multiterminal WSe2 devices with 2D/2D low-temperature Ohmic contacts allows for investigation of the 2D metal-insulator transition. The devices exhibit Ohmic behavior down to 0.25 K and enable accurate determination of carrier density. Measurements show scaling behavior consistent with a metal-insulator quantum phase transition driven by electron-electron interactions and disorder-induced local magnetic moments.

Summary: We present a nanomechanical platform for rapid and sensitive measurements of the spectrally resolved optical dielectric function of 2D materials. The key feature of our approach is the integration of a suspended 2D material into a high Q silicon nitride nanomechanical resonator, which is illuminated by a wavelength-tunable laser source. By analyzing the frequency shift of the resonator and the optical reflection as a function of photon energy, we can obtain the real and imaginary parts of the dielectric function. This method, with its fast response time, high sensitivity, and broad measurement range, offers an attractive alternative to traditional spectroscopic or ellipsometric characterization techniques.

Summary: The chemical simplicity and appealing physiochemical properties of elemental two-dimensional (2D) materials, also known as Xenes, have sparked increasing interest for (opto) electronic, iontronic, and energy applications. Among them, layered α-phase tellurene has shown great promise due to recent advances in its chemical synthesis. However, the electronic and electrochemical properties of tellurene in electrolyte systems remain unclear, hampering its further development. In this study, we investigated the electrostatic gating, electrocatalysis, and electrochemical stability of tellurene in electrolyte systems. Our results demonstrate that tellurene obtained from hydrothermal and chemical vapor deposition methods exhibits thickness-dependent ambipolar transport with high hole mobility and stability in aqueous electrolytes and ionic liquids. Moreover, tellurene shows promising electrochemical properties, such as low Tafel slopes and remarkable stability in acidic electrolytes, as studied using on-chip electrochemistry. These findings provide a comprehensive understanding of the iontronic and electrochemical properties of tellurene, paving the way for its widespread application in sensors, synaptic devices, and electrocatalysis.

Summary: Transition metal sulfides have high potential for sodium storage, but their low conductivity and volume expansion affect their high-rate performance and cycling stability. In this work, a NiS2/FeS heterostructure was constructed by growing Ni-based layered double hydroxide nanosheets on Fe-based Prussian Blue nanocrystals followed by sulfurization. The resulting nanocomposite showed superior rate performance and cycle life compared to the heterostructure-free NiS2 and FeS.
