Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Single-particle states in spherical Si/SiO$_2$ quantum dots

, 2007
We calculate ground and excited electron and hole levels in spherical Si quantum dots inside SiO$_2$ in a multiband effective mass approximation. Luttinger Hamiltonian is used for holes and the strong anisotropy of the conduction electron effective mass ...

Heterostructured Sn:SnO2 Nanodots for High‐Performance Li–S Batteries with Kinetics‐Enhanced Cathode and Dendrite‐Free Anode

Advanced Functional Materials, EarlyView.
Heterostructured Sn:SnO2 nanodots decorated on reduced graphene oxide can simultaneously enhance conversion kinetics and inhibit dendrite growth, enabling stable lithium–sulfur batteries. Abstract The practical application of lithium–sulfur batteries is limited by polysulfide shuttling and sluggish reaction kinetics at the cathode, as well as ...

Additive‐Driven Phase Control for Stable and Efficient CsPbI₃ Solar Cells Via Ambient Low‐Temperature Processing

Advanced Functional Materials, EarlyView.
CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1
