Abstract: A structure (and method) for a piezoelectric device, including a layer of piezoelectric material. A nanotube structure is mounted such that a change of shape of the piezoelectric material causes a change in a stress in the nanotube structure.

Abstract: A Field effect transistor semiconductor switch in which the channel of same is made from materials having an electrical conductivity which can undergo an insulator-metal transistor (i.e., Mott transition) upon application of an electric field. The channel contains the Mott material in which the charge carriers, either holes or electrons, are strongly correlated. The Mott transition determines the metal-insulator switching and is demonstrated to be controlled by an external gate electrode.

Abstract: A display for displaying a color image formed of a plurality of color light components is provided, wherein each color light component has a focal length and a magnification. The display has a light source for providing polarized light of a first polarization and a color filter wheel having segments of different color filters for sequentially separating the polarized light into a plurality of different color lights. Also provided is a directing means for directing the different color lights having the first polarization to a light valve and for directing respective color light components of a second polarization transmitted from the light valve towards a screen. A dynamic focus element is provided in the display for adjusting the focal length and/or magnification of each color light component to minimize chromatic variations between the color light components. Lastly, a lens is provided for magnifying and projecting the adjusted color light components onto the screen to produce the color image.

Abstract: A device for generating radiant energy comprising a first electrode, a second electrode spaced apart from said first electrode, a material disposed between and in electrical communication with first and second electrodes, which emits radiant energy upon activation. This material is a rare earth metal oxide or a rare earth metal halide.
