Abstract
By using liquid nitrogen cooling of sputtered atoms in flowing gas, a cluster machine has been designed. With the machine, kinds of metal and metalnitride clusters have been successfully generated. Cu cluster s micro structure has been studied. Micrography and electron diffraction of different size Cu clusters show:Cu clusters smaller than 8nm in diameter are amorphous,Cu tu culsters larger than 8nm in diameter are in crystal form. Lattice constant of Cu cluster is ...
