Lactone-Terminated Self-Assembled Monolayers for Mimicking Nanoscale Polyester Surfaces

open access: yesChemistry
Two series of lactone-terminated alkanethiol adsorbates with five- and six-membered lactone groups, γ-COCnSH and δ-COCnSH (n = 11, 12), were synthesized and employed to create nanoscale self-assembled monolayers (SAMs) on gold substrates to mimic the ...

Controlling Twisted Angles in Directly Grown MoS2 Bilayers via Tilt Grain Boundary Engineering

open access: yesAdvanced Science, EarlyView.
In this study, the stacking configurations and the growth mechanism of twisted bilayer (TB) MoS2 are systematically investigated, revealing that the relative rotation angle between the two layers is guided by the tilt grain boundary (GBs) of the bottom layer.

Chemically‐Disordered Transparent Conductive Perovskites With High Crystalline Fidelity

open access: yesAdvanced Science, EarlyView.
Kinetically arrested, chemically disordered perovskite thin films exhibit exquisite crystalline fidelity, broad IR–UV transparency, and low resistivity, despite incorporating five mismatched 3d–5d cations, including Cr and W. This study unites electronic correlation, cation diversity, valence complexity, and disorder—enabling new transparent conductors

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

open access: yesAdvanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

Thermal Control of Vortex Motion in Nanoscale Superconductors

open access: yesAdvanced Electronic Materials, EarlyView.
Vortices in superconducting film can be thermally steered by a local heating from a tip. The work shows that the vortex is attracted by the hot spot by a force that emulates an electric field resulting in a fictious Lorentz‐force on the vortex. Abstract Thermally induced motion of vortices in nanoscale superconductors (SCs) is investigated.

Influence of the Twist Angle and Spin–Orbit Coupling on the Interlayer Coupling and Optoelectronic Properties of MoS2/WS2 Superlattice Heterostructures

open access: yesAdvanced Electronic Materials, EarlyView.
This study employs DFT to analyze twist‐angle‐induced interlayer coupling effects in √7 MoS2/WS2 heterostructures. Compared to 2H stacking, 21.79° and 38.21° configurations exhibit weakened coupling, promoting indirect‐to‐direct bandgap transitions trend while suppressing interlayer transitions and low‐frequency Raman modes offering characterization ...
