Azimuthal Dipolar Rotor Arrays on Surfaces
· Ordered arrays of dipolar rotors could thus lead to the fabriion of ferroelectric materials. 20 Such 2D dipolar rotor arrays on surfaces have already been found to undergo collaborative rotation and formation of domains when exposed to sufficiently high STM currents as shown by Rapenne, Hla et al. in a hexagonal network of porphyrin double decker complexes. 16
