Description
Summary:Multi-dot single-electron devices (SEDs) can expect to have high functionality by attaching many input/output terminals. In this paper, Fe nanodot-array-based multi-dot SEDs were fabricated and their single-electron properties were studied. We clarified that although the size of the devices is on the micrometer-scale, clear Coulomb blockade oscillations are observed as a function of the gate voltage. Such large-size devices are relatively easy to be attached by multiple input/output terminals. Therefore, the result suggests that the Fe-nanodot devices can be expected to have a potential to achieve high functionality such as flexible-logic-gate operation.
