    摘要: A solid state photodetector is disclosed comprising a multiplicity of photodetector elements, each element using clamped Geiger mode gain to achieve high sensitivity and high speed. The elements are connected together using a common anode to sum their outputs, allowing operation with gray-scale response over a large total photosensitive area. In the preferred embodiment, high speed performance is achieved by isolating each element from the bias supply by means of an integrated series resistor.

    摘要: A structure and method of fabrication are disclosed for improving surface passivation of III-V compound semiconductors. The invention exploits certain anion-rich compound semiconductors to form a high quality interface with a dielectric when anion mobility is increased during an annealing step. Low post-annealing surface state densities result in a low fixed charge density at the interface and low surface recombination velocities. The invention enables microelectronic devices including diode, transistor, solar cell, photodetector, and CCDs with superior performance wherever prior art devices have inferior surface passivation.

    摘要: The invention, called hypercontacting, achieves a very high level of activated doping at an exposed surface region of a compound semiconductor. This enables production of low resistance ohmic contacts by creating a heavily doped region near the contact. Such region lowers the contact's tunneling barrier by decreasing the extent of the depletion region at the contact, thereby reducing resistance.

    摘要: A novel technique for manufacturing nanostructures and nanostructure is disclosed. The invention exploits techniques to deposit a second semiconductor material on a first semiconductor material with incomplete coverage of the second layer, and forming the nanostructures by filling the holes in the second semiconductor layer with a third semiconductor material. This allows the production of nanowires, nanorods, nanocylinders, and nanotubes with a controllable density and size distribution. Additionally, contact can be made to the bottom of the nanostructures through the first semiconductor layer allowing large area contacts to arrays of nanostructures to be formed. Similarly, contact can be made to the top of the nanostructure by direct deposition of a large area contacting layer. This allows the formation of nanostructure diodes and other nanostructure interconnections. Furthermore, a third large area contact to the second semiconductor layer can be used to modulate the conductivity of the arrays of nanostructures, enabling realization of a wide variety of nano transistors.

    摘要: A fuel for splitting water into hydrogen and an oxide component comprises a substantially solid pellet formed from a solid-like mixture of a solid-state source material capable of oxidizing in water to form hydrogen and a passivation surface layer of the oxide component, and a passivation preventing agent that is substantially inert to water in an effective amount to prevent passivation of the solid-state material during oxidation. The pellets may be introduced into water or other suitable oxidizer in a controlled rate to control the rate of reaction of the source material with the oxidizer, and thereby control the rate of formation of hydrogen. Methods are described for producing the solid-like mixture in varying weight percent of source material to passivation preventing agent.
