SEM tilted views of: (a) GaInP nanowire arrays with NW diameter D = 186, nm and pitch = 500 nm, grown by means of gold-catalyzed MOVPE on InP (111) substrates pre-patterned by using nanoimprint lithography (adapted with permission of Ref. [136], (b) InP NW array with period p = 400 nm, NWs diameter D = 138 ± 4 nm and length L = 1620 ± 40 nm; samples were grown on InP (111) B substrates previously pre-patterned by defining 160 nm diameter and 20 nm high Au catalyst particles in periodic arrays with a pitch of 400 nm using nanoimprint lithography.
