Abstract: Improved methods of bonding solid materials include a step of fabricating a micro-column array (MCA) on at least one surface to be bonded. The MCA formation process can be modified to cause and/or prevent chemical alteration of the surface being treated or to deposit a coating on the surface. In a preferred embodiment, the MCA is fabricated by laser treating the surface, such as by laser ablation.

Abstract: A method for storing energy in a capacitor includes connecting a first conductor to a first electrode and a second conductor to a second electrode. The second electrode is separated from the first electrode by a dielectric layer. The dielectric layer includes a layer of boron oxynitride, BON. The conductivity of the dielectric layer is lower than the conductivity of the first electrode or the second electrode. A voltage of at least 5 volts is applied between the first electrode and the second electrode by means of the first and second conductors.

Abstract: A photodetector having sensitivity in a wide temperature range in both an infrared and an ultraviolet band is provided. The photodetector is formed on a single chip and is designed to be blind to solar or visible radiation. Structures disclosed allow fast and efficient detection of signals with high spatial and temporal resolution. Such sensors may be used for multi-pixel focal arrays and applied for fire detection applications, various space- and military-related applications and other applications. A method for increasing rejection of visible light by the IR sensitive material is also provided.
