Ultraclean Graphene As High Performance Magnetic Field Sensors

A team from Cornell University has fabricated a miniature magnetic field sensor, using an ultrathin graphene "sandwich," that offers detection over a greater temperature change with enough sensitivity to sense subtleties in magnetic fields.

New Photodetector Exceeds 100% Efficiency

A team from Aalto University in Espoo, Finland, has created a black silicon photodetector that has exceeded 100%—the first to surpass what was thought to be the theoretical limit for external quantum efficiency.
