Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

Advanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

Advanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

Advanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.

Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3

Advanced Materials Interfaces, EarlyView.
The subsurface Ba2+disorder, reveals the pairs of O vacancies (VO++$V_O^{ + + }$ s) and small polarons (SPe‐SPe−$SP_e^ - $ s) (Figure a–b), with the charge balance, as the following: Ti3++[VO+++SPe−]pair↔Ti4+${{T}_i}^{3 + } + {{[V_O^{ + + } + SP_e^ - ]}_{pair}} \leftrightarrow T_i^{4 + }$ which is consistent with observed low‐energy electron ...

Investigation for the Temperature Dependence of 2D Electron Gas Behaviors in GaN‐based Multichannel Heterostructures Systems

Advanced Materials Interfaces, EarlyView.
The GaN‐based multichannel heterostructures with larger band conduction difference own better temperature stability. And lattice‐matched heterostructures can improve the temperature stability of the 2D electron gas in the bottom channel. Abstract In this study, 2 electron gas(2DEG) behaviors in Al0.28Ga0.72N/GaN multichannel heterostructures with doped

Chemical Vapor Deposition for the Fabrication of WTe2/h‐BN Heterostructures

Advanced Materials Interfaces, EarlyView.
Chemical vapor deposition (CVD) is studied to produce WTe2 atomic crystals with different morphologies on Si/SiO2 and Si/SiO2/h‐BN substrates. The formation of vertical WTe2/h‐BN heterostructures can be achieved by using a slightly increased temperature as compared to SiO2 substrates, and characterization, including Raman and XPS studies, confirms the ...

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

Advanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...
