" precise control over deposited film's structure, chemistry, thickness, and interfaces with metal electrodes. By chopping each deposited sample in half and looking at its structure atom by atom... a version that precisely mimicked an extremely thin slice of the bulk... film of BaTiO3 in between two metal layers... created tiny capacitors... Applying voltages 100 mV or less... polarization switched within two billionths of second"
