Thermionic emission microscopy of scandium thin film dewetting on W(100)

Scandium thin films of 5-30 nm thickness deposited on clean W(100) surfaces de-wet from the tungsten surface when heated to temperatures < 0.5 Tmelt. The dewetting temperature and the resulting droplet size are a function of the initial scandium film thickness.
