In this work we report recent theoretical calculations of a superconducting island in a strong
vortex confinement regime. The obtained results reveal the evolution of superconducting condensate
as a function of electron mean-free path (l) with the evolution of an applied magnetic field H0. The
results of this study provide an insight about the emergent superconducting properties under such
conditions, using the Ginzburg-Landau numerical simulations where spatial variation of thickness d
on island, omnipresent in these kind of structures grown on Si (111), is taken into account. These
results offer a new route to tailor superconducting circuits by using the controlled bombardment, in
order to explore the impact on vortex distribution, phase of order parameter, number of vortices, free
energy and the first H1 and second critical field H2.
