Abstract:
A microelectromechanical systems (MEMS) element, comprising:a crystalline substrate having a crystal structure characterized by two or more substrate crystal axes; a moveable element moveably attached to the substrate; wherein the moveable element includes a perpendicular portion oriented substantially perpendicular to a plane of the substrate; wherein the perpendicular portion of the moveable element has a crystal structure characterized by one or more moveable element crystal axes; wherein the crystal structure of the perpendicular portion of the moveable element is substantially the same as the crystal structure of the substrate; wherein, when the moveable element is in at least one position, a part of the perpendicular portion projects beyond a surface of the substrate; wherein, when the moveable element is in at least one position, two or more of the moveable element crystal axes are oriented substantially parallel to two or more corresponding substrate crystal axes.
