Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures
Advanced Functional Materials, EarlyView.3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

Polarization features of optically pumped CdS nanowire lasers
, 2014 High quality CdS nanowires suspended in air were optically pumped both below and above the lasing threshold. The polarization of the pump laser was varied while emission out of the end facet of the nanowire was monitored in a 'head-on' measurement ...

Photocurrent measurements in topological insulator $\text{Bi}_2\text{Se}_3$ nanowires
, 2020 Circular photogalvanic currents are a promising new approach for spin-optoelectronics. To date, such currents have only been induced in topological insulator flakes or extended films. It is not clear whether they can be generated in nanodevices.

Gold nanowires from silicon nanowire templates [PDF]
Applied Physics Letters, 2004 We report a simple method for producing gold nanowires (AuNWs) by using silicon nanowires (SiNWs) as templates. Uniform AuNWs were formed in the core of SiNWs, when SiNWs coated with Au were furnace annealed at ∼880 °C at 10−2 Torr. Transmission electron microscopy (TEM) examination showed the AuNWs had diameters of ∼10 nm. High-resolution TEM revealed

Advanced Functional Materials, EarlyView.This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.
