Interparticle heterostructures by spontaneous formation of Dirac nodal arc semimetal PtSn4 domains in nanoparticles produced by Supersonic Cluster Beam Deposition

Marc Heggen, José Enrique Martinez Medina, Emanuele Barborini

In this study, we report on the spontaneous formation of highly ordered 2D layered domains of intermetallic phase PtSn4 in Sn nanoparticles of dimensions of the order of 10 nm duri…
