Single-Walled Carbon Nanotube/Quantum Dot Hybrids for Enhanced Field-Effect-Transistor Performance
- Detailed Technology Description
- Thisinvention comprises a method, compositions and structures associated with anano-network that may enable quantum computing. Traditionally, computersoperate using a binary system. Some formof switch is turned either on or off in a linear fashion, with base computeroperations occurring as a series of 1’s and 0’s. Quantum computers would use an increasednumber of theoretical states, in turn allowing a greater number of processes tobe completed in parallel. Greatlyincreased speed accompanies a greater complexity applied to computing at itsmost fundamental level. In theory,quantum computers could outpace even the most advanced traditional processorsby a rate of a billion to one. Nanostructures have recently shown potential for creating basic computerchips, however carbon nanotubes have been shown to decay easily. Furthermore,the methods used to create existing quantum circuits require extremeconditions, difficult procedures, and expensive materials. Quantum dot technology is arguably the mostpromising 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 blocksof computer chips. These next generation computers will be able to performoperations no classical computer would be able to complete in a reasonableamount of time. As demands for morepowerful data processors will only continue to grow, there are a great numberof potential applications for a smaller and more efficient integrated circuit.
- *Abstract
-
The patentedcomposition and methods encompass what amounts to a totally new approach tocreating microscopic circuits capable of manipulating quantum physics. The electrochemical methods described occurat room temperature, and they are both inexpensive and relatively easy toperform. For these reasons and others, they may provide the means for constructingthe first true quantum computer chip. Scientists at UGA have found a way to capture electrons withinstructures 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, theelectron becomes highly tunable. By layering and configuring these tubes orbundling them together, researchers at UGA have created a network of quantumdots entrapped within microscopic circuitry. Furthermore, they have done so in a fashion that is more affordable,safe, and easy than previously thought possible.
