Abstract: Embodiments of the invention provide for an electron microscope sample holder, which includes a membrane, a support frame partially surrounding a perimeter or circumference of the membrane, a mounting area for mounting a sample to the membrane, where the mounting area abuts a perimeter or circumference of the membrane not surrounded by the support frame, at least two of conducting contact pads mounted on a the support frame, and at least one electrode lead mounted on the membrane and in electric contact with at least one conducting contact pad.

Abstract: A method for patterning nanostructures in a semiconductor heterostructure, which has at least a first layer and a second layer, wherein the first layer has a first surface and an opposite, second surface, the second layer has a first surface and an opposite, second surface, and the first layer is deposited over the second layer such that the second surface of the first layer is proximate to the first surface of the second layer. The method includes the steps of making indentations in a pattern on the first surface of the first layer of the semiconductor heterostructure; bonding the semiconductor heterostructure to a support substrate such that the first surface of the first layer of the semiconductor heterostructure is faced to the support substrate; etching off the second layer of the semiconductor heterostructure; and depositing a third layer over the second surface of the first layer of the semiconductor heterostructure.

Abstract: A device and method for fabricating a device holder for use with a standard holder body of a transmission electron microscope for use with in situ microscopy of both static and dynamic mechanisms. One or more electrical contact fingers is disposed between a baseplate and a frame, with a MEMS device making contact with the electrical contact fingers. A connector is provided to matingly engage the transmission electron microscope and the device holder to couple the device holder to the transmission electron microscope. Once clamped between the baseplate and frame, the electrical contact fingers may be separated from the template.
