Photoluminescence and photocurrent spectroscopy are used as tools to investigate issues such as the size of the band gap, the effects of surface states, and the charge carrier transport in core-shell nanowires. The band gap of InAs1-xPx nanowires with wurtzite crystal structure is measured as a function of the composition for 0.15<x<0.48. The band gap is measured using photocurrent spectroscopy on single InAs nanowires with a centrally placed InAs1-xPx segment. The wurtzite band gap is found to be about 120 meV larger than the corresponding zinc blende band gap ov...
