Single-Walled Carbon Nanotube/Quantum Dot Hybrids for Enhanced Field-Effect-Transistor Performance


Project TitleSingle-Walled Carbon Nanotube/Quantum Dot Hybrids for Enhanced Field-Effect-Transistor Performance
Track Code2004
Short Description

This invention comprises a method, compositions and structures associated with a nano-network that may enable quantum computing. Traditionally, computers operate using a binary system.  Some form of switch is turned either on or off in a linear fashion, with base computer operations occurring as a series of 1’s and 0’s.  Quantum computers would use an increased number of theoretical states, in turn allowing a greater number of processes to be completed in parallel.  Greatly increased speed accompanies a greater complexity applied to computing at its most fundamental level.  In theory, quantum computers could outpace even the most advanced traditional processors by a rate of a billion to one.  Nanostructures have recently shown potential for creating basic computer chips, however carbon nanotubes have been shown to decay easily. Furthermore, the methods used to create existing quantum circuits require extreme conditions, difficult procedures, and expensive materials.  Quantum dot technology is arguably the most promising candidate for use in solid-state quantum computing.  By integrating them within a circuit, scientists may create basic transistors, which in turn are the building blocks of computer chips. These next generation computers will be able to perform operations no classical computer would be able to complete in a reasonable amount of time.  As demands for more powerful data processors will only continue to grow, there are a great number of potential applications for a smaller and more efficient integrated circuit.


The patented composition and methods encompass what amounts to a totally new approach to creating microscopic circuits capable of manipulating quantum physics.  The electrochemical methods described occur at room temperature, and they are both inexpensive and relatively easy to perform. For these reasons and others, they may provide the means for constructing the first true quantum computer chip.  Scientists at UGA have found a way to capture electrons within structures called single-walled carbon nanotubes, often abbreviated to SWCNTs. The trapped electrons embedded within these nanotubes form quantum dots, naturally occurring phenomena with very special properties. Once confined, the electron becomes highly tunable. By layering and configuring these tubes or bundling them together, researchers at UGA have created a network of quantum dots entrapped within microscopic circuitry.  Furthermore, they have done so in a fashion that is more affordable, safe, and easy than previously thought possible.
