Spin Hall Nano‐Antenna

open access: yesAdvanced Science, EarlyView.
ABSTRACT The spin Hall effect is a well‐known phenomenon in spintronics that has found numerous applications in digital electronics (memory and logic), but relatively few in analog electronics. Practically the only analog application in widespread use is the spin Hall nano‐oscillator (SHNO) that delivers a high frequency alternating current or voltage ...

Interfacial Synergy in a Band‐Aligned Low‐Dimensional Heterojunction Toward Broadband Photodetection

open access: yesAdvanced Science, EarlyView.
Monolithically integrating sensing and communication, a Ta2NiSe5/Sb2Te3 heterojunction achieves visible‐to‐near‐infrared photovoltaics with high‐speed terahertz photo‐thermoelectric detection at room temperature. By engineering a Type‐II van der Waals heterojunction, we overcome the intrinsic spectral limitations and disparate physical requirements of ...

From Design to Prototype: High‐Sensitivity Tri‐Mode Operation Photodetectors Based on 1T‐2H Hybrid MoS2

open access: yesAdvanced Science, EarlyView.
This work demonstrates a phase‐engineered MoS2 photodetector that dynamically switches among photocapacitive (PCC), photovoltaic (PV), and photoconductive (PC) modes. By transforming the traditionally parasitic capacitance into an active signal source, the device achieves self‐powered, high‐sensitivity detection with a fast response of 19.2 ms, and a ...

Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse

open access: yesAdvanced Science, EarlyView.
An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Transient Terahertz Oscillations During Photoinduced Polarization Topology Reconfiguration in Ferroelectric Superlattices

open access: yesAdvanced Science, EarlyView.
Terahertz resonances in crystalline heterostructures could close a spectral gap between conventional electronics and photonics while opening new windows on non‐equilibrium lattice dynamics. Femtosecond optical screening of the depolarization field in epitaxial PbTiO3/SrTiO3 superlattices launches a collective polar mode that oscillates near 1 THz and ...

Visible light communications (VLC)

open access: yes, 2015
New solid-state lighting is successfully developing and more efficient LEDs are quickly replacing conventional light sources. This particular scenario offers new possibilities where visible light can also be used for communications, especially in electromagnetic sensitive areas as are aircrafts, presenting a solution to the looming electromagnetic ...

Multimodal Super‐Resolution Imaging of Nitrogen‐Vacancy Centers via High‐Index‐Induced Structured Illumination Microscopy and Optically Detected Magnetic Resonance Spectrometry

open access: yesAdvanced Science, EarlyView.
This work demonstrates a multimodal super‐resolution imaging technique for nitrogen‐vacancy centers by integrating high‐index‐induced structured illumination with optically detected magnetic resonance. By utilizing diamond's high refractive index, the method achieves sub‐100‐nm spatial resolution and enhanced localization. This dual‐modulation strategy
