Figure 3: Results of Stark spectroscopy measurements.

From: Generation and control of polarization-entangled photons from GaAs island quantum dots by an electric field

Figure 3

PL peak positions of the exciton (closed-up triangles) and the biexciton (closed-down triangles) with the electric field. The electric field dependence of the biexciton binding energy (BXX), which is defined as the energy difference between the exciton and the biexciton emissions, is also shown and indicated by open circles. The left scale corresponds to the exciton and the biexciton data, and the right scale corresponds to the BXX data; both scales are referred to by arrows. The solid lines represent the parabolic fits to the data, from which p and β are extracted.
