Computer simulation of electrified water/platinum interfaces

A molecular dynamics simulation of a water lamina between the (100) faces of two platinum walls was performed with a superimposed constant electric field of 10¹⁰ V/m. The platinum/water interface consists of two highly structured water layers within a distance of 6.5 Å. In the middle of the lamina the water is homogeneous and bulk-like. Thus, strong changes of the electrostatic potential occur across the water interphases, and the potential profile is almost linear in the inner region
