An integrated transmission electron microscope comprising multiple electron sources for tuned beams of ultrafast, scanning probe, and parallel illumination in varied beam energies can be alternated within sub-microseconds onto a sample with dynamic 'transient state' processes to acquire atomic-scale structural/chemical data with site specificity. The various electron sources and condenser optics enable high-resolution imaging, high-temporal resolution imaging, and chemical imaging, using fast-switching magnets to direct the different electron beams onto a single maneuverable objective pole piece where the sample resides. Such multimodal in situ characterization tools housed in a single microscope have the potential to revolutionize materials science.

Integrated transmission electron microscope

A microelectromechanical system (MEMS) device can be used for quantitative mechanical testing of materials within a controlled (chemical and temperature) environment, with the ability for electrochemical control to the specimen, that is coupled with a complimentary in-situ characterization technique.

Active mechanical-environmental-thermal MEMS device for nanoscale characterization

Ion-doped metal or ceramic nanoparticles can be added into, for example, a component that upon exposure to an environmental stimulus, will release the ion and 'tattle' on any impending destruction.

Tattletale ion-implanted nanoparticles

Ion implantation can be used to define a thermal dissipation path that allows for better thermal isolation between devices in close proximity on a microelectronics chip, thus providing a means for higher device density combined with better performance.

Ion-implanted thermal barrier

Ion beam modification of noble metal electrical contact coatings can achieve suitable friction and wear behavior with inherently stable low ECR. For example, this method of producing Au electrical contact coatings can produce wear properties similar to electroplated hard Au, but without the environmental concerns due to stringent OSHA regulations on the use and disposal of toxic chemicals associated with Au electroplating baths. Integration of physical vapor deposition techniques with ion implantation can produce noble metal coatings with surfaces modified to achieve the desired balance between adhesion/friction/wear and electrical contact resistance on a commercial scale.

Ion beam modification of noble metals for electrical contacts

An optical second-harmonic generator (or spontaneous parametric down-converter) includes a microresonator formed of a nonlinear optical medium. The microresonator supports at least two modes that can be phase matched at different frequencies so that light can be converted between them: A first resonant mode having substantially radial polarization and a second resonant mode having substantially vertical polarization. The first and second modes have the same radial order. The thickness of the nonlinear medium is less than one-half the pump wavelength within the medium.

Second harmonic generation in resonant optical structures

A single crystal micromechanical resonator includes a suspended plate of lithium niobate or lithium tantalate. The suspended plate and a support structure are formed from a single crystal.

Single crystal micromechanical resonator

The present invention relates to a single crystal micromechanical resonator. In particular, the resonator includes a lithium niobate or lithium tantalate suspended plate. Also provided are improved microfabrication methods of making resonators, which does not rely on complicated wafer bonding, layer fracturing, and mechanical polishing steps. Rather, the methods allow the resonator and its components to be formed from a single crystal.
