Episode 4: Imaging device tracks and controls photocurrent streamlines in electronic devices
Manage episode 401117473 series 2602554
In this podcast episode, MRS Bulletin’s Sophia Chen interviews Nathan Gabor from the University of California, Riverside about his group’s work on imaging and directing the flow of electrons in electronic devices. They designed their device by taking a crystal of yttrium iron garnet, which does not conduct electricity, and putting a nanometers-thick layer of platinum, which does conduct electricity, on top of it. When they illuminate the device with a laser, this device produces an electric current. They further discovered that when they combine the crystal with the platinum, the interface between the two materials exhibits magnetic properties. Gabor’s research team used this sensitivity to a magnetic field to steer the electron flow in the device. This work was published in Proceedings of the National Academy of Sciences.
