The field-effect technique, popular thanks to its application in commonfield-effect transistors, is here applied to metallic thin films by using as adielectric a novel polymer electrolyte solution. The maximum injected surfacecharge, determined by a suitable modification of a classic method ofelectrochemistry called double-step chronocoulometry, reached some units in10^15 charges/cm^2. At room temperature, relative variations of resistance upto 8%, 1.9% and 1.6% were observed in the case of gold, silver and copper,respectively and, if the films are thick enough (> 25 nm), results can benicely explained within a free-electron model with parallel resistive channels.The huge charge injections achieved make this particular field-effect techniquevery promising for a vast variety of materials such as unconventionalsuperconductors, graphene and 2D-like materials.
