Arthur Nowick and Siegfried Mader rolling different sized balls into an inclined tray

(L-R): Arthur Nowick and Siegfried Mader, scientists of the Internationl Business Machines Corporation showing that by rolling different sized balls into an inclined tray, they can duplicate what happens when atoms from hot metallic vapors are frozen directly onto a cold surface.  This model is the first to give such complete insight into how different metal atoms group together to form thin alloy films. Such films are fabricated for study and possible use in advanced electronic circuitry. Because they are made by depositing metals directly from a vapor, without going through a liquid stage, they do not follow the traditional rules of metallurgy. The model provides an excellent means of achieving a deeper understanding of this new area of metallurgy. The model shows, for example, that if the diameter of the balls differs substantially, the balls will arrange themselves into an amorphous or homogeneous structure. This and other insights gained from the model are in qualitiative agreement with behavior of atoms in the formation of these new films, Credit Line: AIP Emilio Segrè Visual Archives, Physics Today Collection
