Nh. Peng et al., 2D Monte Carlo simulation of proton implantation of superconducting YBa2Cu3O7-delta thin films through high aspect ratio Nb masks, NUCL INST B, 164, 2000, pp. 979-985
Perturbation of proton beam damage profile due to sidewall interactions in
very high aspect ratio implant masks has been studied using Monte Carlo sim
ulations. The model structure is composed of amorphous Nb metal mask, cryst
alline high temperature superconducting YBa2Cu3O7-delta (YBCO) thin film, a
nd amorphous LaAlO3 substrate. The simulation results reveal the existence
of enhanced proton beam penetration in target materials due to sidewall int
eractions. (C) 2000 Elsevier Science B.V. All rights reserved.
