A transfer layer includes a transparent substrate. A buffer layer is formed on the transparent substrate that comprises PbO, GaN, PbTiO3, La0.5Sr0.5CoO3 (LSCO), or LaxPb1-xCoO3 (LPCO) so that separation between the buffer layer and the transparent substrate occurs at substantially high temperatures.

摘要:
A flexible high-voltage thin-film transistor includes a gate electrode, a source electrode, a drain electrode, a dielectric layer, and a flexible semiconductor layer. The flexible semiconductor layer serves as a channel for the transistor and is in electrical communication with the source electrode and the drain electrode. The drain electrode is laterally offset from the gate electrode. The dielectric layers is configured and arranged with respect to other elements of the transistor such that the transistor is stably operable to facilitate switching of relatively high drain voltages using relatively small controlling gate voltages.

The presently disclosed invention provides for the fabrication of porous anodic alumina (PAA) films on a wide variety of substrates. The substrate comprises a wafer layer and may further include an adhesion layer deposited on the wafer layer. An anodic alumina template is formed on the substrate. When a rigid substrate such as Si is used, the resulting anodic alumina film is more tractable, easily grown on extensive areas in a uniform manner, and manipulated without danger of cracking. The substrate can be manipulated to obtain free-standing alumina templates of high optical quality and substantially flat surfaces. PAA films can also be grown this way on patterned and non-planar surfaces. Furthermore, under certain conditions the resulting PAA is missing the barrier layer (partially or completely) and the bottom of the pores can be readily accessed electrically. The resultant film can be used as a template for forming an array of nanowires wherein the nanowires are deposited electrochemically into the pores of the template. By patterning the electrically conducting adhesion layer, pores in different areas of the template can be addressed independently, and can be filled electrochemically by different materials. Single-stage and multi-stage nanowire-based thermoelectric devices, consisting of both n-type and p-type nanowires, can be assembled on a silicon substrate by this method.

A quadrupole mass filter (QMF) is provided. The QMF includes a plurality of rectangular shaped electrodes aligned in a symmetric manner to generate a quadrupole field. An aperture region is positioned in a center region parallel to and adjacent to each of the rectangular shaped electrodes. An incoming ion stream enters the aperture region so as to be controlled by the quadrupole field. A plurality of voltage sources provide a r.f. and d.c. signal to the electrodes for generating the quadrupole field. An auxiliary voltage source applies an auxiliary drive signal to the r.f. and d.c. signal to create new stability boundaries within the standard Mathieu stability regions with high-resolution around operating conditions where there are approximately no higher-order resonances.

The formation of diaphragms by silicon wafer bonding provides for a structure having at least two such diaphragms with cavities in the wafers to which the diaphragm layer is bonded. Passageways through the wafers provide for communication of a fluid to the diaphragms. In some locations less than all of a plurality of diaphragms may be bonded to only one wafter having a cavity adjacent the diaphragm.
