Figure 2.

Effect of drain and source capacitances of the SiNW-FET as well as electrolyte parameters to the frequency spectrum. TTF spectrum of the SiNW-FET with varying source capacitance (C_ps) for two scenario of drain capacitance with C_pd = 0 fF (a) and C_pd = 33 fF (b). (c) Effect the drain capacitance (C_pd) while the source capacitance is equal to 50 fF. As C_pd is introduced, a peak appears in the TTF spectra. An increase in C_pd leads to a change in the amplitude and in the position of the peak. (d) Effect of conductivity of electrolyte on the TTF spectra. The peak amplitude decreases with the decrease of electrolyte concentration.
