| Abstract: | Presently, there is a rapid growing interest in quantum devices based on single-electron-tunneling (SET)-effects. Such SET-devices are possible candidates for single electron memories that might allow room temperature operation. The focus of possible room temperature SET-devices is towards fabrication of lateral tunnel structures. We have during the last years developed a new way to fabricate lateral quantum devices. The principle is based on the use of the atomic force microscope (AFM) for very accurate movement of pre-fabricated nano-objects into a small gap between two metal electrodes. In this way a unique technique to build extremely small scale and accurate structures for contacting of nano-objects is realized, making hitherto unachievable devices to be formed. |
