Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

Ultrathin Gold for Robust Multi‐Element Surface Plasmon Resonance Biosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
This is a pioneering work where for the first time we applied recently synthesised ultrathin layer of gold for plasmonic biosensing that makes use of multi‐element architectures. This study solves the problem of stability of the multi‐element biosensors as well as demonstrates increased sensitivity achieved by utilising new additions to low‐dimension ...

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.
