Summary: This study investigates the impact of contact scaling on FET performance by examining Au contacts to monolayer MoS2 FETs with reduced channel length (LCH) and contact length (LC). The results show that when LC is scaled from 300 to 20 nm, Au contacts exhibit a reduction in the ON-current of approximately 2.5x, from 519 to 206 mu A/ mu m.

Summary: This study addresses the challenge of interface incompatibilities in composite polymer electrolytes (CPEs) by phosphatizing the LLZO surfaces, which ensures high air stability and suppresses PVDF-HFP dehydrofluorination. This improves the uniform distribution of ceramic and polymer phases, enhances ionic conductivity and transference number, and provides exceptional cycling performance for Li/CPE and cathode/CPE interfaces. This study highlights the importance of achieving electro-chemo-mechanical compatibilities for CPEs and offers a new waste to wealth route.

Summary: Poly(ethylene oxide) (PEO) and Li6.75La3Zr1.75Ta0.25O12 (LLZTO)-based composite polymer electrolytes (CPEs) are improved by coating LLZTO fillers with a functional supramolecular combination (CD-TFSI). This coating allows for homogeneous dispersion and tight interface contact, resulting in enhanced conductivity, increased Li+ transference number, and extended electrochemical stability window. Practical application of the CPEs is demonstrated in both full cells and pouch cells. This work presents a new strategy for optimizing PEO/LLZTO CPEs for solid lithium batteries.

Summary: Incomplete lattice transition in heterojunction preparation can create a new crystal phase, which enhances photocatalytic activity by providing a new transfer channel for charge carriers. In this study, a hydrothermal synthesis of BaTiO3 and alpha-Bi2O3 composite induced a lattice transition of alpha-Bi2O3 to gamma-Bi2O3. Besides the alpha-Bi2O3/BaTiO3 interface, a new BaTiO3/gamma-Bi2O3 contact was formed, enabling the transfer of charge carriers. The optimal alpha-Bi2O3/BaTiO3/gamma-Bi2O3 sample demonstrated significantly higher removal efficiencies for norfloxacin and lomefloxacin, reaching 93% and 95% respectively, compared to pure phases and diphasic heterojunction samples.

Summary: Adhesion energy, a crucial quantity in various fields, determines the mechanical behavior and failure of interfaces. However, there is a lack of systematic and accurate first-principles determination of heterostructure adhesion energy due to the difficulties in simulating systems with different lattices. In this study, we have developed a robust workflow to search for optimal interface geometry and accurately determine adhesion energies for metallic heterostructures, creating a database of accurate values for technological applications. This allows us to benchmark empirical relations and improve their predictability using easily measurable or computable quantities.

Summary: High-performing 2D electrical and optical devices require an ideal van der Waals (vdW) metal contact. This study proposes a method for forming vdW contacts using a sacrificial Se buffer layer, which results in a stable and ideal vdW interface. The study investigates the difference in Schottky barrier height between vdW metal contacts made with buffer layer, transferred, and directly deposited methods. The results show that the Se buffer layer method forms the most stable and ideal vdW contact, preventing Fermi-level pinning.
