From Random Telegraph to Gaussian Stochastic Noises: Decoherence and Spectral Diffusion in a Semiconductor Quantum Dot

Figure 4

Schematic sketch of the heterostructure (under reverse bias) displaying the conduction and valence band edges energy along the growth direction. The applied gate voltage 𝑉_𝐺 is superimposed on the Schottky voltage 𝑉_𝑆 of the order of −1.5 V for our structure.
