An apparatus for finishing a cut edge of a glass laminate includes a support including a surface and an edge, a rail disposed adjacent the support and extending substantially parallel to the edge, a carrier coupled to the rail, and a finishing tool coupled to the carrier and including an abrasive surface positioned adjacent the edge. The carrier is translatable along the rail to translate the abrasive surface relative to the edge. A method includes securing a glass laminate to a support and contacting a cut edge of the glass laminate with an abrasive surface of a finishing tool coupled to a carrier. The carrier is translated along a rail to move the abrasive surface along the cut edge of the glass laminate and transform the cut edge into a finished edge. The glass laminate can have an edge strength of at least about 100 MPa.

The present invention relates to a freestanding, thick, single crystalline gallium nitride (GaN) film having significantly reduced bending deformation. The inventive GaN film having a crystal tilt angle of C-axis to the &#x3c;0001&#x3e; direction per surface distance of 0.0022&#xb0;/mm exhibits little bending deformation even at a thickness of 1 mm or more, and therefore, is beneficially used as a substrate for a luminescent device.
