  • Method to reduce dislocation density in silicon using stress
    Patent number: 8389999
    Abstract: A crystalline material structure with reduced dislocation density and method of producing same is provided. The crystalline material structure is annealed at temperatures above the brittle-to-ductile transition temperature of the crystalline material structure. One or more stress elements are formed on the crystalline material structure so as to annihilate dislocations or to move them into less harmful locations.
    Type: Grant
    Filed: September 28, 2010
    Date of Patent: March 5, 2013
    Assignee: Massachusetts Institute of Technology
    Inventors: Anthony Buonassisi, Mariana Bertoni, Ali Argon, Sergio Castellanos, Alexandria Fecych, Douglas Powell, Michelle Vogl

  • Glazing panels
    Patent number: 6495261
    Abstract: Glazing Panels suitable for vehicle windscreens comprise a solid coloured obscuration band (24) around the perimeter, a fade out band (26) extending inwardly therefrom and a multilayer transparent infra-red reflective and/or absorbing coating (28) have the outer edge of the coating positioned so as to lie within the fade out band (26). The panel reduces reflection caused by the transition between coated and uncoated areas of the glass. The panels may be laminates or bilayers.
