Irish Walking the Plank Solar Cell Nanowire Arrays Probed in situ by Surface%2
Surface physics play an outsized role in nanostructured electronic devices such as solar cells. Surface potential microscopy (SPM) provides a unique and relevant characterization (electrical, structural), even in unconventional 3D geometries. We unveil a flexible, non-destructive AFM technique for directly measuring nanowires (NW) within an array still on the growth substrate. This cross-sectional
