Popis: Single phase Ca 2 Si layers are successfully grown on Mg 2 Si/Si substrates for the first time. These Mg 2 Si and Ca 2 Si layers are formed by heat treatment of Si and Mg 2 Si/Si substrates in Mg and Ca vapor, respectively. The replacement of Ca atoms with Mg in Mg 2 Si leads to the formation of single phase Ca 2 Si layers. It is confirmed that the formation of other silicide phases is suppressed, when the layers are grown under optimum growth time. The structural property of the resultant layers is examined by X-ray diffraction technique, scanning electron microscopy and transmission electron microscopy.
