Au(111) is sputtered onto freshly cleaved Mica substrates. Flame annealing is suggested before use.
Atomically flat terraces are typically several hundreds of nanometers cross, with this size increasing after hydrogen flame annealing. Gold plated Mica is available in thicknesses ranging from 50Å to 2500Å. AXIM can also provide custom thicknesses based upon the client's requirements.
