UA Scientists have tracked electrons moving through exotic
materials that may make up the next generation of computing hardware, revealing
intriguing properties not found in conventional, silicon-based semiconductors.

gallium oxide field effect transistor with an optically defined gate. From near
(bottom) to far (top): the source, gate, and drain electrodes. Metal is shown
in yellow and orange, dark blue represents dielectric material, and lighter
blue denotes the gallium oxide substrate. Credit: AFRL Sensors Directorate at WPAFB, Ohio, US
Schematic of the structure and the fabrication process of
Yang's spine-like battery. (a) Schematic illustration of bio-inspired
design, the vertebrae correspond to thick stacks of electrodes and soft
marrow corresponds to unwound part that interconnects all the stacks.
(b) The process to fabricate the spine-like battery, multilayers of
electrodes were first cut into designed shape, then strips extending out
were wound around the backbone to form spine-like structure.
