Sublimation of Cleaved Surface of Zinc Single Crystals. II. Interpretation and Discussion

概要

論文の詳細を見る
Cleaved surfaces of zinc single crystals were sublimed. The fact that the sublimedlayer thickness of 29 qm evaluated from the observed deposited thickness 0.3 qm ofthe film is almost equal to the depth of 22 qm of the recess engraved on the cleaved sur-face indicates the possibility of particle ejection. The sublimed mass 1.9 g evaluatedfrom the Hertz-Knudsen formula with the evaporation coefficient (Y = I is larger thanthe initial specimen mass of 0.57 g. The thickness, 34 jtm, of the deposited film, esti-mated from the Hertz-Knudsen formula with cc=1, is larger than the observedthickness of 0.3 pm, Scanning electron micrographs and evaluation of the sublimedmass and the film thickness indicate the inapplicability of the atomic evaporationtheory.
