Fc. Beuran et al., MOLECULAR-BEAM EPITAXY OF A SINGLE ATOMIC LAYER - EXPERIMENTAL RESULTS FOR CUPRATES AND LATTICE-GAS SIMULATIONS, Physica. C, Superconductivity, 282, 1997, pp. 631-632
The adsorption efficiency (Y) was measured for Ca and Sr during the sy
nthesis of cuprate compounds belonging to the BSCCO and (Sr;Ca)CuO fam
ilies. A strong variation of Y with the incident flux is observed. Thr
ee distinct ranges of flux are described, which lead to very different
growth processes. We developed a 2D lattice-gas simulation model whic
h reproduces, qualitatively, this behaviour.
