Memristor-based nano-crossbar computing is a revolutionary computing paradigm that does away with the traditional Von Neumann architectural separation of memory and computation units. The computation of Boolean formulas using memristor circuits has been a subject of several recent investigations. Crossbar computing, in general, has also been a topic of active interest, but sneak paths have posed a hurdle in the design of pervasive general-purpose crossbar computing paradigms. Various embodiments are disclosed which demonstrate that sneak paths in nano-crossbar computing can be exploited to design a Boolean-formula evaluation strategy. Such nano-crossbar designs are also an effective approach for synthesizing high performance customized arithmetic and logic circuits.

Apparatus for generating a truly random binary bit value in which the resistance of memristive devices serve as the analogue bit values. Resistance values and the randomness by which they are generated stems from the inherently non-uniform, irreproducible variations in the materials of which the system is composed.

A method of controlling the resistivity of gallium nitride is disclosed. The method incorporates an MBE system and utilizes solid source gallium, gaseous source nitrogen and solid source Buckminster Fullerene C as a carbon dopant for the GaN film. A desired, predetermined GaN film resistivity can be created during the growth process by selecting the temperature of the effusion cell containing the C within a predetermined range so as to impart the desired resistivity in the GaN film.
