This cross-sectional transmission electron microscope image shows a sample used for the charge-to-spin conversion experiment. The nano-sized grains of less than 6 nanometers in the sputtered topological insulator layer created new physical properties for the material that changed the behavior of the electrons in the material.

communicate with devices implanted deep within the human body. Image: courtesy of the researchers
Plastic deformation of crystalline materials is
caused by nucleation and multiplication of dislocations under an external force
(A and B). It has been generally believed that brittle inorganic semiconducting
materials have difficulty in formation of dislocations because of their strong
chemical bonds. However, researchers found that a great number of dislocations
are generated and multiplied in ZnS crystals during deformation in darkness
(C), resulting in the extraordinary plasticity that researchers observed. Image courtesy of Atsutomo Nakamura.
TU Wien has developed a sensor for measuring the strength of electric
fields, which is smaller, simpler and less prone to distortion than
comparable devices.Picture: Tiny new sensor - compared to a one-cent-coin
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.
