From: SiGe nanocrystals in SiO2 with high photosensitivity from visible to short-wave infrared

Normalized photocurrent spectra taken on S1 samples biased at −1.5 V (a) 700 °C, (b) 800 °C and (c) 1000 °C RTA for 15 min. Also, photocurrent spectra taken on S2 samples annealed at 800 °C for 10 min and biased at −1 V: (d) measured at room temperature (RT) and (e) at 100 K. The frequency of modulated light was 80 Hz. Each graphic contains as inset the corresponding spectral responsivity.
