Abstract

Nanointerfaces of mobile, thin spherical shells of light ions that expand on the femtosecond time scale, can be produced by Coulomb explosion of extremely ionized molecular heteroclusters consisting of light and heavy ions, e.g., (D+|q+)n (q = 7-35), which are generated in ultraintense laser fields (intensity, I, = 1016 to 1020 W·cm-2). Modeling, together with molecular dynamics simulations, reveals the expansion of 2D monolayers with high energies and narrow energy distributions [e.g., Eav ≃ 23 keV and ΔE/Eav = 0.16 for D+ from (D+l25+)2171] arising from kinematic run-over effects. The expanding regular, monoionic, spherical nanointerfaces manifest the attainment of transient self-organization in complex systems driven by repulsive Coulomb interactions.
