The article entitled “Thermal stability of thin Au films deposited on salt whiskers” has been just published in Acta materialia. Ehud was the main driving force behind this beautiful work. He developed a method of growing thin and long single crystalline KCl whiskers, and coated them with gold film. The solid state dewetting of these core-shell whiskers has always started at the whisker edges – and now we know why! This is an important contribution to the understanding of thermal stability of thin metal films with complex three-dimensional architecture.
