Room-temperature operation of multifunctional single-electron transistor logic

Successfully fabricated SETs operating at room temperature with the highest peak-to-valley current ratio (PVCR) ever reported, and demonstrated, for the first time, the room-temperature operation of a SET/CMOS hybrid circuit. In addition, the authors have verified that the function of a SET-pMOS circuit can be programmed from a converter/inverter to an inverter/converter by utilizing a nonvolatile memory function incorporated in the SET, suggesting that the programmable multiple functionality will be realized in logic circuits consisting of SETs with a nonvolatile memory function. These results open a new way to the realization of future low-power super-design-flexible field-programmable logic LSIs by using SETs having a memory function.
