Formation of periodic structure on the surface of the FNW.
(a–c) Are secondary electron images of a FNW scanned at 380 °C. (b,c) Are secondary electron images of same position as indicated by the green square in (a). (d,e) Are images of FNW scanned at 490 °C. (d,e) Are area overlapped with (c). Indicative patterns in (c) were marked in (d,e) to show their positions. The details of periodic and non-periodic surface in (d,e) was shown in (d-1,d-2,e-1,e-2,e-3), respectively.
