摘要
The minority carrier lifetimes of VLS-grown axial p-n junction silicon nanowires are characterized by the reverse recovery transients of electrically injected minority carriers. Nanowire-diameter-dependent lifetimes and various electrical properties indicate the enhanced surface recombination with decreasing diameters, suggesting the significance of surface passivations for effective carrier transport in photovoltaic applications.
