The Nanomechanical Bit

The potential of nanomechanical devices for nanomechanical memory and logic operations is considered. Various device approaches are discussed including nano ‐electromechanical systems in silicon and carbon nano‐tube switches, and combinations of nanomechanical resonators. With their scalability, robustness, and outstanding power efficiency, a new avenue for computing devices is naturally expected in conjunction with quantum mechanical circuits. AbstractThe applicability of nanomechanical devices for computational approaches is reviewed. The focus is on the representation and processing of information based on nanomechanical bits. Several device concepts are discussed ranging from nano ‐electromechanical systems in silicon to circuits based on carbon nano‐tube switches, combinations of nanomechanical resonators and traditional transistors, and integration into a computing architecture. The strengths of mechanical systems include their scalability, robustness to external electr ical shocks, and their low‐energy consumption. Hence, they may lead the way to new forms of ultradense memory and alternative routes of computing. In conjunction with quantum mechanical single electron circuits, nano‐electromechanical systems may also have potential for quantum computational cir cuits.
