The cover picture of this issue is related to the Feature Article by Rohit P. Prasankumar (pp. 1973–1995). The figure depicts the schematic of an ultrafast optical pump-probe measurement on an ensemble of semiconductor nanowires. The figures shown on the right demonstrate the ability of ultrafast optical spectroscopy to track the temporal evolution of carrier populations in semiconductor nanowires with femtosecond time resolution as a function of intrinsic parameters (e.g., the nanowire diameter) and extrinsic parameters (e.g., the wavelength or excitation fluence), providing vital information that cannot be obtained by any other technique.
