A nanowire electronmechanical device with an improved structure and a
method of fabricating the same prevent burning of two nanowires which are
switched due to contact with each other while providing stable on-off
switching characteristics. The nanowire electromechanical device
comprises: an insulating substrate; first and third electrodes spaced
apart from each other on the insulating substrate, wherein a negative
voltage and a positive voltage, varying within a predetermined range, are
applied to the first and third electrodes, respectively; a second
electrode interposed between the first and third electrodes, a constant
positive voltage, lower than the voltage applied to the third electrode,
being applied to the second electrode; a first nanowire vertically grown
on the first electrode and charged with a negative charge; a second
nanowire vertically grown on the second electrode and charged with a
positive charge; and a third nanowire vertically grown on the third
electrode and charged with an amount of positive charge corresponding to
the magnitude of the varying voltage applied to the third electrode.
