Low Temperature MOCVD Synthesis of High‐Mobility 2D InSe

open access: yesSmall, EarlyView.
We report on the low‐temperature, wafer‐scale metal‐organic chemical vapor deposition (MOCVD) growth of phase‐pure two‐dimensional indium selenide (InSe). By adjusting the Se/In ratio and temperature, we mapped In‐rich to Se‐rich InxSey phase space and identified the conditions that produce epitaxial, layered InSe. Structural and spectroscopic analyses

Interface‐Engineered Bi0.5Sb1.5Te3/WSe2 Heterostructures for Enhanced Thermoelectric Performance

open access: yesSmall, EarlyView.
BST/WSe2 heterostructures grown by pulsed laser deposition exhibit semicoherent van der Waals interfaces, characterized by lattice strain, compressed gaps, and localized moiré patterns. These interfacial features modulate carrier generation and energy filtering, yielding high Seebeck coefficients and a consistently high power factor above 50 µW cm−1 K ...

Fast Switching and High Polarization in Ferroelectric Hf0.5Zr0.5O2 Films

open access: yesSmall Science, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 thin films are grown under tuned redox conditions to simultaneously achieve high polarization and fast switching. Control of defect dipoles and internal fields enables stable domain wall motion without compromising performance. This work provides a pathway for designing fast and energy‐efficient ferroelectric devices.

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

open access: yesSmall Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Preparation of Aqueous Solutions with Information on Solids Using Natural Polymers by Solid‐State Mixing

open access: yesThe Chemical Record, EarlyView.
The solid‐state information, such as chiral crystal formation, crystal polymorphism, mechanochromism, room‐temperature phosphorescence, and fluorescence detection by molecular recognition, is maintained even when the functional guest molecules are solubilized in water using natural polymers.
