  • Phase transformation in transition metal dichalcogenides
    Patent number: 9673390
    Abstract: Devices including transition metal dichalcognides and methods of forming and operating such devices are disclosed. In one disclosed method, a layer of a transition metal dichalcogenide is provided, and a phase transformation of at least a region of the layer of the transition metal dichalcogenide is induced.
    Type: Grant
    Filed: February 20, 2015
    Date of Patent: June 6, 2017
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: Evan J. Reed, Karel-Alexander Duerloo, Yao Li

  • Piezoelectric apparatuses, systems and methods therefor
    Patent number: 9246078
    Abstract: Various aspects as described herein are directed to piezoelectric materials. As consistent with one or more embodiments, an apparatus includes a nanomaterial and structures coupled to the nanomaterial. This nanomaterial-structure combination manifests piezoelectric characteristics, via the combination. In certain implementations, neither the nanomaterial nor the coupled structures independently exhibit piezoelectric characteristics, yet do so in combination.

  • Method for generation of THz frequency radiation and sensing of large amplitude material strain waves in piezoelectric materials
    Patent number: 7788980
    Abstract: Strain waves of THz frequencies can coherently generate radiation when they propagate past an interface between materials with different piezoelectric coefficients. Such radiation is of detectable amplitude and contains sufficient information to determine the time-dependence of the strain wave with unprecedented subpicosecond, nearly atomic time and space resolution.
