Researchers in the Netherlands have proposed a conceptual
design of a molecular motor. Although it currently only exists on paper, it is
based on "electric field actuation and electric current detection of the
rotational motion of a molecular dipole embedded in a three-terminal,
single-molecule device."
The design consists of anchoring groups that connect the
backbone to the loads, which allow for the measurement of low-bias conductance.
A dipole rotor is driven by an oscillating gate field located underneath. The
rotating moiety outfitted with a permanent electric dipole is part of a
conjugated molecule that is suspended between two metallic contacts above a
gate electrode.
Do you think this idea is realistic?
