SUMMARY:Ultrafast diffusion at the onset of 2D growth: O/Ru(0001) and S/Ni

DESCRIPTION:The mechanisms that underpin growth at surfaces are of increas
 ing interest as 2D materials are explored for applications. Here\, I prese
 nt an experimental study of clustering dynamics observed during ultrafast 
 surface motion\, measured using helium-3 spin echo (HeSE) spectroscopy. I 
 will discuss two systems that exhibit islanding phenomena\, namely O/Ru(00
 01) and S/Ni(111)\; each is measured at high temperatures\, corresponding 
 to picosecond-timescale diffusion which has been inaccessible using past t
 echniques\n\nJoin on your computer\, mobile app or room device\n"Click her
