Scanning tunneling microscopy of Ni and Fe nanocrystals on SrTiO3

Thesis

The equilibrium crystal shapes (ECS) of Ni and Fe were investigated on three different terminations of SrTiO₃ {(001), (110), and (111)}. Firstly, to investigate surface reconstructions, SrTiO₃ substrates were subjected to various thermal cycles. SrTiO3 is capable of producing a multitude of surface reconstructions such as (2 × 1), (2 × 2), (√5 × √5) R26.6°, and c(4 × 2) on (001) termination; (4 × 1) on (110) termination; and (4 × 4) and (6 × 6) on (111) termination.
