Fig. 8From: Photoconductivity, pH Sensitivity, Noise, and Channel Length Effects in Si Nanowire FET SensorsNoise spectra of NW FET, measured in different pH solutions. Spectral dependence of LF noise for NW with length, l = 10 μm, measured at T = 300 K and several pH values: 6.3, 7.0, and 8.2 at VBG = − 5 V, VFG = − 1 VBack to article page
