  abstract = {We investigated the photoelectrochemical properties of both n- and
	p-type (In,Ga)N nanowires (NWs) for water splitting by in situ electrochemical
	mass spectroscopy (EMS). All NWs were prepared by plasma-assisted
	molecular beam epitaxy. Under illumination, the n-(In,Ga)N NWs exhibited
	an anodic photocurrent, however, no O2 but only N2 evolution was
	detected by EMS, indicating that the photocurrent was related to
	photocorrosion rather than water oxidation. In contrast, the p-(In,Ga)N
	NWs showed a cathodic photocurrent under illumination which was correlated
	with the evolution of H2. After photodeposition of Pt on such NWs,
	the photocurrent density was significantly enhanced to 5 mA/cm2 at
	a potential of −0.5 V/NHE under visible light irradiation of ∼40
	mW/cm2. Also, incident photon-to-current conversion efficiencies
	of around 40% were obtained at −0.45 V/NHE across the entire visible
	spectral region. The stability of the NW photocathodes for at least
	60 min was verified by EMS. These results suggest that p-(In,Ga)N
	NWs are a promising basis for solar hydrogen production.},
