Electric-field-dependent photoconductivity in CdS nanowires and nanobelts : exciton ionization, Franz–Keldysh, and Stark effects

Electric-field-dependent photoconductivity in CdS nanowires and nanobelts : exciton ionization, Franz–Keldysh, and Stark effects

We report on the electric-field-dependent photoconductivity (PC) near the band-edge region of individual CdS nanowires and nanobelts. The quasi-periodic oscillations above the band edge in nanowires and nanobelts have been attributed to a Franz–Keldesh effect. The exciton peaks in PC spectra of the...
