Caption: UWM Professor Carolyn Aita shows one of the "targets" used to form thin films in her "sputter deposition" equipment. In sputter deposition, energetic ions formed from a vapor bombard the target, sending energetic atoms from it scattering like billiard balls in a game of pool. Those atoms then coat the substrate in ultra-thin layers.
