An on-nanowire (on-NW) band-graded photodetector that pertains to the on-nanowire composition gradation from pure Si to pure Ge, Si1–xGex (0 ≤ x ≤ 1), is reported. The spectral onset of interband photocarrier generation and photocurrent amplitude are on-NW de-multiflexed over the continuously varying energy band gap and surface trap state density in an individually addressable manner.
