The nanomechanical actuator/oscillator device comprising nanobimorphs, such as nanotubes, designed such that inducing a difference in charge density between the tubes (e.g. by biasing one tube positive with respect to the other with sufficient tube-to-tube contact resistance) induces lateral movement in the end of the bimorph, forming a nanoscale resonator, as well as a force sensor when operated in an inverse mode. A method of producing a novel nanobimorph structure with integrated electrodes is also provided.

    摘要： A semiconductor device has a multilayer doping to provide improved passivation by quantum exclusion. The multilayer doping includes at least two doped layers fabricated using MBE methods. The dopant sheet densities in the doped layers need not be the same, but in principle can be selected to be the same sheet densities or to be different sheet densities. The electrically active dopant sheet densities are quite high, reaching more than 1×1014 cm−2, and locally exceeding 1022 per cubic centimeter. It has been found that silicon detector devices that have two or more such dopant layers exhibit improved resistance to degradation by UV radiation, at least at wavelengths of 193 nm, as compared to conventional silicon p-on-n devices.

    摘要： An improved cathodoluminescence light collection system for use in electron microscopes provides an optical fiber, the facet or aperture of which is positioned adjacent the sample. The cathodoluminescence light, collected by the optical fiber in this manner, may be used to provide spectrally resolved cathodoluminescence images of the sample as well as local cathodoluminescence spectra of the type available in prior art cathodoluminescence light collection systems, but without incurring the numerous disadvantages of such prior art light collection systems. The present invention is relatively inexpensive, far easier to maintain because it does not require use of a mirror and, it is more compact in size thereby making it compatible with the physical limitations of more electron microscopes.

The coatings made in accordance with the techniques set forth by the invention are shown to be capable of forming silicon CCD detectors that demonstrate world record detector quantum efficiency (>50%) in the near and far ultraviolet (155 nm-300 nm). The surface engineering approaches used demonstrate the robustness of detector performance that is obtained by achieving atomic level precision at all steps in the coating fabrication process. As proof of concept, the characterization, materials, and exemplary devices produced are presented along with a comparison to other approaches.
