Item Open Access Design and fabrication of CSWAP gate based on nano-electromechanical systems(Springer, Cham, 2016) Yüksel, Mert; Erbil, Selçuk Oğuz; Arı, Atakan B.; Hanay, M. SelimIn order to reduce undesired heat dissipation, reversible logic offers a promising solution where the erasure of information can be avoided to overcome the Landauer limit. Among the reversible logic gates, Fredkin (CSWAP) gate can be used to compute any Boolean function in a reversible manner. To realize reversible computation gates, Nano-electromechanical Systems (NEMS) offer a viable platform, since NEMS can be produced en masse using microfabrication technology and controlled electronically at high-speeds. In this work-in-progress paper, design and fabrication of a NEMS-based implementation of a CSWAP gate is presented. In the design, the binary information is stored by the buckling direction of nanomechanical beams and CSWAP operation is accomplished through a mechanism which can selectively allow/block the forces from input stages to the output stages. The gate design is realized by fabricating NEMS devices on a Silicon-on-Insulator substrate. © Springer International Publishing Switzerland 2016.Item Open Access Nanoelectromechanical switches for reconfigurable antennas(2010) Cetiner, B.A.; Bıyıklı, Necmi; Yildirim, B.S.; Damgaci, Y.We report on the full-wave analyses of a frequency reconfigurable antenna integrated with metallic nanoelectromechanical system (NEMS) switches (length = 3 μm, width = 60 nm). The NEMS switch used in this work has the same architecture with low voltage, double-arm cantilever-type metallic DC-contact microelectromechanical system (MEMS) switch recently developed in author's group. The microfabrication and characterization of the MEMS switch have also been given in this article.

L.Reliable operation of a miniaturized mechanical system requires that nanomechanical motion be transduced into electrical signals (and vice versa) with high fidelity and in a robust manner. Progress in transducer technologies is expected to impact numerous emerging and future applications of micro- and, especially, nanoelectromechanical systems (MEMS and NEMS); furthermore, high-precision measurements of nanomechanical motion are broadly used to study fundamental phenomena in physics and biology. Therefore, development of nanomechanical motion transducers with high sensitivity and bandwidth has been a central research thrust in the fields of MEMS and NEMS. Here, we will review recent progress in this rapidly-advancing area.
