摘要： A thin film resonator (TFR) is produced with an improved piezoelectric film which is epitaxially grown on a growing surface, resulting in a piezoelectric film with less grain boundaries. Epitaxial growth refers to the piezoelectric film having a crystallographic orientation take from or emulating the crystallographic orientation of a single crystal substrate or growing surface. For example, by epitaxially growing a piezoelectric film on a single crystal silicon substrate as the growing surface, an improved piezoelectric film is produced with little or no grain boundaries. Also provided is a method of making a TFR in which the piezoelectric film is grown on a substrate. Subsequently, a portion of the substrate is removed, and the electrodes are deposited on either side of the piezoelectric film.

摘要： An effusion source comprises a vitreous C filament and a heater to increase the temperature of the filament to produce a C vapor. Also described is a deposition method comprising (a) depositing a layer of material on a substrate, and (b) during step (a), heating a body of material that includes vitreous carbon so that carbon from the body is vaporized and incorporated into the deposited layer.

摘要： A hot-electron bolometric mixer/detector, which uses the nonlinearities of the heated two-dimensional electron gas medium, is described. Electrons in the illustrative embodiment of the present invention are “velocity-cooled” rather than “diffusion-cooled” or “phonon-cooled” like hot-electron bolometric mixer/detectors in the prior art. The illustrative embodiment is velocity-cooled when the elastic mean-free path of the electrons is greater than the channel length, L, of the mixer/detector. In this case, the motion of the hot electrons is more accurately modeled by their speed rather than in accordance with diffusion models. This leads to a mixer/detector with a wider modulation bandwidth at a lower power than is exhibited by mixer/detectors in the prior art.
