Single particle energies as functions of substrate orientation. Several lowest (ground state, black/boxes; first excited state, red/circles; second excited state, blue/triangles, etc.) single particle electron (a) and hole (b) energies and single particle gap (c) of InAs/InP nanowire quantum dot (h = 2.4 nm, d = 18 nm).
