Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr

open access: yesAdvanced Functional Materials, EarlyView.
A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.

Ultrahigh‐resolution (λ/10) Femtosecond Laser Writing of Polymer‐Encapsulated Multicolor Perovskite Patterns Beyond the Diffraction Limit

open access: yesAdvanced Functional Materials, EarlyView.
Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.

Laser Interference Lithography [PDF]

open access: yes, 2011
In this chapter we explain how submicron gratings can be prepared by Laser Interference Lithography (LIL). In this maskless lithography technique, the standing wave pattern that exists at the intersection of two coherent laser beams is used to expose a ...

Sonication‐Assisted Palladium Nanogaps in a Capacitive Structure: A Tunable and Reliable Solution for Sensitive Hydrogen Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a capacitive hydrogen sensor with a simple structure and process. Sonication‐induced Pd nanogaps modulate the effective electrode area in response to hydrogen concentration, resulting in capacitance changes within a range predefined by physical parameters.

Symmetry Enhanced Unconventional Spin Current Anisotropy in a Collinear Antiferromagnet

open access: yesAdvanced Functional Materials, EarlyView.
Spin‐orbit torques (SOTs) are investigated in epitaxial FeSn, a topological antiferromagnet with kagome lattice symmetry. Combining experimental and theoretical approaches, the study identifies a six‐fold conventional damping‐like spin‐orbit torque (DL SOT), along with the coexistence of both six‐fold and uniaxial unconventional field‐like torque (FL ...
