Summary on Grant Application Form |
|
In recent years, much of the research in microelectronics has focused on the development of devices which operate using the wave-nature of the electron. Of these quantum-effect devices, the most promising is the single-electron transistor in which the Coulomb blockade effect is used to control precisely the electrons in the device. Single-electron transistor memories have been extensively researched, but the device can also be used as the basis of Coulomb blockade logic where each bit of information is represented by one or at most tens of electrons, compared to the tens of thousands of electrons used in a conventional logic circuit. In this proposal, new concepts for Coulomb blockade logic, and the design and fabrication of Coulomb blockade logic circuits will be investigated using technology compatible with industrial practice. The successful development of these circuits enhances the prospect of future microprocessor/memory systems with very low power consumption and extremely high levels of circuit integration.
