Movie of Growth of Cu on Cu(001) by R. Gerlach and L. Douillard
(click on the image to view the movie)
A pyramid-like structure produced by successive sequences of step
flow growth and on top nucleation. Pyramid basis consists of static
step bunches. During deposition the steps move outwards, i.e. the
center is the top of the pyramid.
The video sequence consists of 111 images and shows a total time of
550 s, i.e. 9min and 10s of Cu growth on Cu(111) at 128°C sample
temperature. The Deposition Flux was 161s/ML.
The LEEM images with a field of view of 3.0µm were taken at an
Electron energy of the incident electrons of 3.2 eV.
Growth parameters: Deposition Flux = , 6.2 10-3 ML/s (1040°C), 161
s/ML, Sample Temperature = 401 K (128°C)/
