O.6 ML CS2 on Gold:

CS2 islands on gold, growth directed by herringbones

Islands of CS2 growing out from gold step

 

 

 

O.05 ML CS2 on Gold:

CS2 nucleated at bottom of gold step, standing waves on upper terrace

 

 

 

 

 

1 ML CS2 on Gold:

 

Molecular herringbone structure of CS2 domains, gold reconstruction visible
