چکیده
n-InGaN/p-Cu 2 O core-shell nanowire (NW) p–n junctions enable efficient self-powered photoelectrochemical photodetectors (PEC PDs) in the visible. The photocurrent density under one-sun illumination is enhanced by 8 times compared to that of bare InGaN NW PEC PDs due maximized photocarrier separation built-in electric field junction. responsivity reaches 173 ?A/W illumination. response 30–40 ms are among shortest achieved for PDs. Together with long-time stability and reusability, a robust, easy fabricate, operate PD introduced.

Simultaneously efficient light absorption and charge separation in WO3/BiVO4 core/shell nanowire photoanode for photoelectrochemical water oxidation.
We report a scalably synthesized WO3/BiVO4 core/shell nanowire photoanode in which BiVO4 is the primary light-absorber and WO3 acts as an electron conductor. These core/shell nanowires achieve the highest product of light absorption and charge separation efficiencies among BiVO4-based photoanodes to date and, even without an added catalyst, produce a photocurrent of 3.1 mA/cm(2) under simulated...
متن کاملEvaluation of Doping in GaP Core-Shell Nanowire pn Junction by Off-Axis Electron Holography
Semiconductor nanowires (NWs) are very promising building blocks for future electronic and optoelectronic devices. Realizing this, nevertheless, requires overcoming several important challenges, such as control and evaluation of doping levels in NWs. Due to the nanoscale nature of NWs, characterization techniques, such as Hall effect measurements and four-point probes, used conventionally for t...
متن کاملSi/InGaN core/shell hierarchical nanowire arrays and their photoelectrochemical properties.
Three-dimensional hierarchical nanostructures were synthesized by the halide chemical vapor deposition of InGaN nanowires on Si wire arrays. Single phase InGaN nanowires grew vertically on the sidewalls of Si wires and acted as a high surface area photoanode for solar water splitting. Electrochemical measurements showed that the photocurrent density with hierarchical Si/InGaN nanowire arrays in...
متن کاملHigh-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode towards photoelectrochemical water splitting.
Many narrow band-gap semiconductors cannot fulfil the energetic requirements for water splitting, thus the assistance of large external voltages to complete the water decomposition reaction is required. Through thermal decomposition of Fe(NO3)3 on n-Si nanowires prepared by the chemical etching method, we fabricated a high-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode that exhib...
متن کاملHierarchical TiO2–Si nanowire architecture with photoelectrochemical activity under visible light illumination†
Bandgap engineering of TiO2 is a substantial strategy for efficient water splitting in the visible light range. Introducing dopants and hydrogenation have been found effective for that purpose. In this paper, we report the development of a hierarchical three dimensional TiO2–Si nanowire (NW)-based photoelectrochemical (PEC) anode with visible light photochemical activity. The TiO2 NWs were synt...
