Topological Hysteresis in the Intermediate State of Type-I Superconductors

, 2005
Magneto-optical imaging of thick stress-free lead samples reveals two distinct topologies of the intermediate state. Flux tubes are formed upon magnetic field penetration (closed topology) and laminar patterns appear upon flux exit (open topology).

Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Superconducting Magnetic Shield.

TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1995
A superconductor is an ideal material for shield, giving excellent attenuation of electric/magnetic fields from DC to very high frequency. It is particularly useful for low frequency region shields because there is no effective material which gives effective shielding performance.
