Identification and Reversible Optical Switching of NV+ Centers in Diamond

open access: yesAdvanced Functional Materials, EarlyView.
NV+ centers in diamond are predicted to coexist with NV0 and NV– centers, but direct experimental confirmation remains challenging. Using positron annihilation spectroscopy with in situ light illumination, a charge transition NV+/0 is observed at 1.234(8) eV.

Q-Analogues of Parallel Numerical Scheme Based on Neural Networks and Their Engineering Applications

open access: yesApplied Sciences
Quantum calculus can provide new insights into the nonlinear behaviour of functions and equations, addressing problems that may be difficult to tackle by classical calculus due to high nonlinearity.

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

open access: yesAdvanced Functional Materials, EarlyView.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Low‐Loss Far‐Infrared Surface Phonon Polaritons in Suspended SrTiO3 Nanomembranes

open access: yesAdvanced Functional Materials, EarlyView.
The low‐loss, highly confined, and thickness‐tunable surface phonon polaritons are demonstrated in the far‐infrared regime within transferable freestanding SrTiO3 membranes, achieving high figures of merit comparable to the previous record values from the vdW materials.

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

open access: yesAdvanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...
