Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

open access: yesAdvanced Materials, EarlyView.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

Dielectric and Gate Metal Engineering for Threshold Voltage Modulation in Enhancement Mode Monolayer MoS2 Field Effect Transistors

open access: yesAdvanced Materials, EarlyView.
Enhancement‐mode monolayer MoS2 FETs with low threshold voltage are essential for low‐power electronics. The threshold voltage can be tuned by the gate metal work function when the semiconductor/dielectric interface is clean. Interfaces between monolayer MoS2 and ZrO2 or hBN allow effective work‐function modulation of the threshold voltage, in contrast

High‐Mobility and Low‐Voltage Top‐Gate Transistors Comprising an InSnO–InSnWO Channel Layer and a Polymethyl Methacrylate Dielectric Layer

open access: yesAdvanced Materials Interfaces, EarlyView.
The top‐gate thin film transistors (TFTs) combining the advantages of both the inorganic InSnWO channel layer and the organic polymethyl methacrylate dielectric layer were prepared. The optimized TFTs exhibit excellent performance, including a high mobility (> 60 cm2 V−1 s−1), a low threshold voltage (< 0.50 V; positive value), and robust stabilities ...
