Publication number: 20140169104Abstract: Embodiments of tunneling barriers and methods for same can embed molecules exhibiting a monodispersion characteristic into a dielectric layer (e.g., between first and second layers forming a dielectric layer). In one embodiment, by embedding C60 molecules inbetween first and second insulating layers forming a dielectric layer, a field sensitive tunneling barrier can be implemented. In one embodiment, the tunneling barrier can be between a floating gate and a channel in a semiconductor structure. In one embodiment, a tunneling film can be used in nonvolatile memory applications where C60 provides accessible energy levels to prompt resonant tunneling through the dielectric layer upon voltage application. Embodiments also contemplate engineered fullerene molecules incorporated within the context of at least one of a tunneling dielectric and a floating gate within a nonvolatile flash memory structure.Type: ApplicationFiled: December 23, 2013Publication date: June 19, 2014Applicants: NANO-C, INC., CORNELL UNIVERSITYInventors: Edwin C.

Patent number: 7833493Abstract: A mode of combustion and multi-component reactor to accomplish this mode of combustion are disclosed which produces fullerenes and fullerenic material by combustion. This mode consists of de-coupling an oxidation region of a flame from a post-flame region, thus giving greater control over operating parameters, such as equivalence ratio, temperature, and pressure; allows conditions of the operating parameters of the combustion reaction to be attained which would not be easily attained by conventional methods; and offers the ability to more easily stabilize the combustion reactions to allow for higher throughputs of fuel and oxidant. Several embodiments of a primary zone of a multi-component reactor are also disclosed. Said primary zone serves as the oxidation region, operates on the principle of providing recycle to the reacting combustion mixture, and which may be operated as approximately a well-mixed reactor.Type: GrantFiled: May 27, 2008Date of Patent: November 16, 2010Assignee: Nano-C, Inc.Inventors: Jack B.
