Fig. 5From: In Silico Modeling of Indigo and Tyrian Purple Single-Electron Nano-Transistors Using Density Functional Theory Approach E(q, V G ) as a function of V G for indigo (a) and Tyrian purple (b) SET nanodevices. This function was calculated in the SET environment. Different curves represent different charge states of the natural dye molecule, blue (−2), green (−1), red (0), turquoise (1), and violet (2)Back to article page
