R. Vanselow et Xqd. Li, ACCELERATED VAPOR GROWTH CAUSED BY ROUGHENING TRANSITIONS IN THE VICINAL AREAS OF RH(111) AND RH(110), Surface science, 301(1-3), 1994, pp. 120000229-120000234
Vapour growth as a function of sample temperature was studied with FEM
in the clean vicinal areas of Rh{lll) and Rh{11O}. A fairly steady gr
owth was observed up to about 700 K: Classical growth at T<T-c (T-c=ro
ughening transition temperature). The growth rate increased steeply at
720 K along the [211]) edges of {111} and at 680 K along the [100] ed
ges of {110}: Accelerated growth at T>T-c.(T-c({110}/[211])=720 K;T-c(
{110}/[100])=680 K.) (A roughening of the {110} face itself could not
be observed.) The rapid growth at T greater than or equal to T-c is in
agreement with a prediction by Burton and Cabrera (1949).
