“Green” Aqueous Synthesis, Structural, and Optical Properties of Quaternary Cu2ZnSnS4 and Cu2NiSnS4 Nanocrystals

physica status solidi (b), EarlyView.
Novel Cu–Ni–Sn–S nanocrystals (NCs) stabilized with thioglycolic acid are synthesized in aqueous solutions. The structural and optical properties of Cu–Ni–Sn–S NCs are examined in colloidal solutions and thin films and compared to those of Cu–Zn–Sn–S NCs. The absorption coefficient is α > 104 cm−1 at 400 nm with an estimated Eg≈2.2 eV.

Low Resistivity Sputter Deposited SnOx Thin Films: An Indium‐Free Transparent Conductive Oxide?

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
For sustainable, mass‐producible optoelectronic devices, indium‐free transparent conductive oxides are essential. This study examines how oxygen content during sputter deposition and thermal treatments influences the optoelectrical properties of amorphous SnOx films.

Structural and Transport Properties of Thick and Thin Cr2AlC Films

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
This study compares structural and transport properties of Cr2AlC thin films (50 and 500 nm) systematically disordered by ion irradiation. Columnar grain growth is observed only in 500 nm films, while both films exhibit a weak fiber texture. Kondo scattering from displaced Cr atoms leads to a resistivity upturn, with distinct magnetoresistance in each ...

Vortex Ratchet Effect in Superconductor Open Nanotubes and 3D Nanoflakes

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Magnetic flux quanta in 3D superconductor nanotubes move in the regions where the normal component of the applied magnetic field is close to maximum. Asymmetric pinning sites placed in these areas result in an enhanced vortex ratchet effect compared to planar systems.

Nonreciprocal Entanglement of Frequency‐Distinct Qubits

Advanced Quantum Technologies, EarlyView.
This work demonstrates the first spatiotemporal superconducting metasurface for nonreciprocal entanglement between frequency‐mismatched qubits at millikelvin temperatures. Leveraging space‐time‐modulated Josephson field‐effect transistors (JoFETs), the platform enables unidirectional, spurious‐free quantum state conversion with high efficiency.
