Theoretical Study of the Kinetics Mechanism Underlying GaN Epitaxy Growth on 4H‐SiC Substrate

open access: yesAdvanced Materials Interfaces, EarlyView.
Control the structure and polarity of epitaxial GaN on 4H‐SiC substrate with precise interfacial configuration. Ga‐polar wz‐GaN with Si‐HT configuration, N‐polar wz‐GaN with Si‐TM and C‐TH configurations, whereas non‐polar 4|8 GaN with C‐MT configuration resulting from the polarity competition of GaN nucleation, respectively.

Scaled‐Up Graphene Growth Through Chemical Vapor Deposition Over Large‐Area Liquid Cu Catalysts

open access: yesAdvanced Materials Interfaces, EarlyView.
Scaling up the catalyst area fivefold and improving molten catalyst cleaning minimize reactor kinetic effects, enabling reaction kinetics to dominate graphene growth. This results in high‐quality graphene with controlled layering and measurable nucleation rates.

Evolution of the Electronic Gap of Directly Synthesized Versus Mechanically Transferred WS2 Monolayer to Multilayer Films

open access: yesAdvanced Materials Interfaces, EarlyView.
The electronic properties of tungsten disulfide (WS₂) films are investigated using ultraviolet photoelectron and inverse photoemission spectroscopies (UPS/IPES). Differences in electronic gaps and energy levels between mechanically transferred and MOCVD‐grown films reveal the non‐negligible influence of preparation methods on electronic properties ...

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

open access: yesAdvanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.
