  In sharp contrast to the prevailing view that electric fields promote water
freezing, here we show by molecular dynamics simulations that monolayer ice
confined between two parallel plates can melt into liquid water under
perpendicularly applied electric field. The melting temperature of the
monolayer ice decreases with the increasing strength of the external field due
to field-induced disruption of the water-wall interaction induced well-ordered
network of hydrogen bond. This electromelting process should add an important
new ingredient to the physics of water.
