• either thermal evaporation (heating Al in a boron nitride crucible with a tungsten filament) or electron beam evaporation onto a commercial TEM grid (SiOx; Fa. Plano, Wetzlar). Aluminium buffer layer (10 nm) deposition was monitored by means of a quartz crystal microbalance (Cressington MTM 10). After

• with thicknesses of 10 nm, 20 nm, 40 nm and 60 nm on the pre-patterned substrates using electron beam evaporation at a base pressure of 2 × 10−7 mbar. Film thicknesses were determined by the quartz crystal monitor and then verified by profilometer measurements (Dektak 150 – Veeco). After deposition
