7. Current–voltage characteristics
Fig. 3. (Colour online.) Natural logarithm of the current density J/J0J/J0 at ε = (1,1,1) against the gate voltage VebVeb for the two values of the applied voltage Vcb=0Vcb=0 (curve 1, black) and 0.4 V (curve 2, red) if Ef=0.01 eVEf=0.01 eV, and Vcb=0.4 VVcb=0.4 V if Ef=0.04 eVEf=0.04 eV (curve 3, blue). The structural parameters LY-411575 the same as in Fig. 2(b) and J0=1.6×10−5 A/nm2J0=1.6×10−5 A/nm2.Figure optionsDownload full-size imageDownload as PowerPoint slide
In the case of room temperature (Θ=300 KΘ=300 K), the oscillatory behaviour shown in Fig. 3 also takes place, with the same position of peaks. However, the following two distinctions are found: (i) the oscillatory form computed in this figure for zero temperature is shifted up increasing the current J, so that the higher temperature, the upper shifting, and (ii) the peak to valley ratios in the current–voltage characteristic are decreasing with increase of temperature. It would be possible to confirm these properties by direct numerical calculations using Eqs. (28) and (29), however, cardiovascular system is more useful to analyse how they appear.
