    • The change in the Ge-Sb-Te composition from that in ref. 5 was made for making comparisons with optical phase changes easier. The electrode film was changed from 200 nm-thick Pt to 20 nm-thick Au-Ni because of its smaller surface roughness.

    • 4 cantilevers, Au-Ni gave good durability, probably because Au-Ni is harder than Au and Pt, The tip curvature (without metal coating) is reported to be 20 nm in a data sheet (Veeco, DNP-S), and accordingly, it may increase to ∼50 nm with the coating.

    • Temperature rises by imaging scans can be envisaged, while the rise may enhance the crystal growth.
