A team of researchers from Argonne’s Materials Science Division and Northern Illinois University, working with researchers at Argonne’s Center for Nanoscale Materials, report two new findings on tungsten ditelluride: (1) WTe2 is electronically three-dimensional with a mass anisotropy as low as 2, and (2) the mass anisotropy varies with temperature and follows the magnetoresistance behavior of the Fermi liquid state. The results not only provide a general scaling approach for the anisotropic magnetoresistance but also are crucial for correctly understanding the electronic properties of WTe2, including the origin of the remarkable “turn-on” behavior in the resistance versus temperature curve, which has been widely observed in many materials and assumed to be a metal-insulator transition.

Scientists gain insight into origin of tungsten ditelluride's magnetoresistance

Two new significant findings may move scientists closer to understanding the origins of tungsten ditelluride's extremely large magnetoresistance, a key characteristic in modern electronic devices such as magnetic hard drives and sensors.

An international team of scientists has discovered how to measure the resistance of a nanomembrane to both bending and stretching by rolling it into a tube and performing a single experiment to measure the tube's bending resistance along its length. Previous methods required two experiments: one to measure a nanomembrane's bending resistance and another to measure its stretching resistance. The discovery is expected to aid researchers working to make three-dimensional objects and devices from two-dimensional membranes only one nanoparticle thick. The transmission electron micrograph on the right was obtained at Argonne’s Center for Nanoscale Materials.  (Click for larger view.)
