摘要： A deformable reflector includes a plurality of MEMS devices, each having an electrode membrane having a reflective surface thereon, a flat surface, and a pulldown electrode formed in the flat substrate. The electrode membrane has substantially a same flatness of the flat substrate when the electrode membrane comes into contact with the flat substrate across a majority of its surface area in response to a voltage being applied to the pulldown electrode. The electrode membrane has a two-dimensional curvature when no voltage is applied to the pulldown electrode.

摘要： The high-pixel-count uncooled thermal imaging arrays disclosed herein have liquid crystal (LC) microcavity transducers separate from the read-out integrated circuit (ROIC). The transducer converts incident infrared (IR) radiation in birefringence changes that can be measured with visible light. In other words, the system uses the temperature sensitivity of the LC birefringence to convert the IR scene to a visible image. Measurements on sample arrays indicate that the LC material quality is similar to that of bulk samples and has good noise performance. Additionally, high-fill-factor arrays on fused-silica substrates may be processed to enable optimization of conditions for greatly improved temperature sensitivity. An additional IR absorber layer may be integrated into the process to tune the structure for the infrared.

摘要： A mechanical memory transistor includes a substrate having formed thereon a source region and a drain region. An oxide is formed upon a portion of the source region and upon a portion of the drain region. A pull up electrode is positioned above the substrate such that a gap is formed between the pull up electrode and the substrate. A movable gate has a first position and a second position. The movable gate is located in the gap between the pull up electrode and the substrate. The movable gate is in contact with the pull up electrode when the movable gate is in a first position and is in contact with the oxide to form a gate region when the movable gate is in the second position. The movable gate, in conjunction with the source region and the drain region and when the movable gate is in the second position, form a transistor that can be utilized as a non-volatile memory element.

摘要： Improvements in shallow-homojunction solar cells based upon a plurality of layers of a direct gap semiconductor material such as GaAs, as well as their fabrication, are disclosed. The shallow-homojunction solar cells have a n.sup.+ /p/p.sup.+ structure in which the n.sup.+ top layer is limited to a thickness which permits significant carrier generation to occur in a lower semiconductor layer. An anodic antireflection coating is applied over the n.sup.+ top layer, and a particularly preferred method for applying the antireflection coating is by anodization. These solar cells can be grown on relatively inexpensive substrates, if desired, such as silicon or germanium.
