An important issue in nanoelectromechanical systems is developing small electrically driven motors. We report on an artificial nanofabricated motor in which one short carbon nanotube moves relative to another coaxial nanotube. A cargo is attached to an ablated outer wall of a multiwalled carbon nanotube that can rotate and/or translate along the inner(More)
: The possibility that an adsorbed molecule could provide shallow electronic states that could be thermally excited has received less attention than substitutional impurities and could potentially have a high impact in the doping of silicon nanowires (SiNWs). We show that molecular-based ex-situ doping, where NH3 is adsorbed at the sidewall of the SiNW, can(More)
Following the last E-nano Newsletter special double issue dedicated to semiconductor nanowires (NW), this edition contains an article providing new insights in this relevant field for future nano-electronics applications, i.e. the computational tools used to simulate their structural, electronic and transport properties. Nanowire-based devices offer unique(More)
Many resistive switching memory devices are based on the formation of a small-area conducting filament (CF). Understanding the conduction and switching properties of the CFs is crucial for their industrial application. In this work we report electrical evidence of atomic-size effects in metal-insulator-metal structures showing memory switching. In(More)
