Defect Detection in Magnetic Systems Using U-Net and Statistical Measures

This paper demonstrates that robust defect detection in fluctuating magnetic systems, such as Ni80Fe20, can be achieved by training U-Net models on statistical descriptors like temporal mean, standard deviation, and latent entropy derived from micromagnetic simulations, provided the training data accurately reflects the expected noise statistics.

Impacts of Fermi Level Pinning at Hole-Selective Contacts in CdSeTe/CdTe Solar Cells

This paper presents a device physics model demonstrating that Fermi-level pinning by donor-like defects at the p-ZnTe/p-CdSeTe hole-selective contact causes downward band bending and fill factor losses in CdSeTe/CdTe solar cells, while suggesting that passivating these interfaces could significantly enhance efficiency, particularly in thinner devices with longer carrier diffusion lengths.

Bridging the lab-to-fab gap in non-fullerene organic solar cells via gravure printing

This study demonstrates that the performance gap between laboratory and industrial roll-to-roll gravure-printed non-fullerene organic solar cells stems from device architecture and optical losses rather than intrinsic material physics, establishing a roadmap for high-efficiency manufacturing using commercially available materials and non-halogenated solvents.

Collapse of Jahn-Teller Phonons in La1x_{1-x}Srx_{x}MnO3_3 with Weak Magnetoresistance

High-resolution neutron scattering and DFT studies on La1x_{1-x}Srx_{x}MnO3_3 reveal that despite weak magnetoresistance, Jahn-Teller-active oxygen vibrations collapse above the Curie temperature due to giant electron-phonon coupling driving diffusive oxygen distortions, suggesting that the magnitude of magnetoresistance correlates with the rate of this diffusion rather than the strength of the coupling itself.
