Figure 3From: Chaos-based true random number generators Characterization of chaotic oscillation. (a) Current and (b) density plot of the electric field vs time, showing how the dipole occasionally fails to reach the receiving contact; (c) Fourier spectrum of the current; (d) phase diagram of the electric field (in kV/cm) at wells 45 and 46, showing how the chaotic oscillations fill a mussel-shaped region; (e) multifractal dimension. Applied voltage: 7.3513V.Back to article page
