Polyyne-containing carbons are transformed to multi-wall carbon nanotubes (CNTs) in a transmission electron microscope. This technique has an advantage to observe the CNT growth in an in-situ way, and the CNTs have been found to grow in a two-step process: quick formation (a few seconds) of rod-like carbons, and slow formation (1 min) of the hollows inside the rods accompanied by graphitization of...
The molecular arrangement of copper phthalocyanine (CuPc) on atomically flat Si(001)-(2 1)-H was studied with atomic force microscopy and complimentary techniques. Images obtained on 10-20 nm thick films indicate that the column of stacked molecules lie parallel to the surface, in contrast to the case on flat Si(111)-(1 1)-H where the column stands perpendicular to the surface. The lateral...
