Resumen:
In this study we present results concerning the early growth stages of an insulator-metal interface by means of scanning tunnelling microscopy. In particular, we reportthe growth of aluminium fluoride (AlF3) islands over a Cu(100) surface at room temperature, from sub-monolayer coverages up to 1.25 monolayers. These islands coverthe substrate with a single monolayer film up to depositions of 0.80 monolayers, with 3D growth beyond thiscoverage. High voltages (V ≥ 2.50 V) are needed to obtain STM images, showing the insulator character of the AlF3 islands. Important modifications are observed in theAlF3/Cu(100) surface after an annealing treatment.
