Figure 3From: Ultrafast Carrier Relaxation in InN Nanowires Grown by Reactive Vapor TransportDifferential absorption signal versus time delay for different photon wavelengths in InN NWs. Photoexcitation was accomplished with 3.1 eV photons under a pump fluence of 50 μJ/cm2at room temperature. The inset shows the differential absorption signal as a function of probing photon energy at time delays of 0, 0.5, and 1.0 psBack to article page
