Fig. 6From: Self-Seeded MOCVD Growth and Dramatically Enhanced Photoluminescence of InGaAs/InP Core–Shell Nanowiresa Normalized PL spectra of InGaAs/InP core−shell nanowires with different Xv (Xv = 30%, 35%, and 40%) at 77 K. b Temperature dependent PL spectra of InGaAs/InP core−shell nanowires with Xv = 40%. Inset in b shows corresponding temperature dependent shift in PL peak energyBack to article page
