N2 - The authors have developed a fabrication method for suspended metallic single-electron transistorsSETs utilizing a combination of conventional angle evaporation technique and ashing of theunderlying organic polymer. The authors’ Al-based suspended devices exhibit clear Coulombblockade effects typical for conventional SETs. The measured low-frequency charge noise is ratherlow but still within the range reported for conventional Al devices. We suggest that the noise levelcan be further reduced by decreasing the effective SET temperature.
