Fig. 2

Raman spectra of (a) InP(111)B crystal, (b) InAs(111)B crystal, (c) InP nanopillar, (d) InP/InAs/InP nanopillar, and (e) InP/InAs/InP nanocones. The green dot lines are corresponded to InAs A1(TO), InAs E1(TO), InAs A1(LO), InAs E1(LO), InP E1(TO), InP A1(LO), InP E1(LO), InP E1(2TO), InP E1(TO+LO), and InP E1(2LO) in sequence
