Line Plot from Scientific Research

A similar set of data but obtained using 3.1 eV excitation, which is above the CM threshold. As distinct from a , even the lowest intensity traces exhibit a fast bi-excitonic component (top) whose time constant (middle) is similar to that obtained using low photon excitation. Another distinction is a strong deviation of the measured < N X > (symbols; bottom panel) from the Poisson dependence (solid black line; bottom panel). In particular, the low-< N ph > limit is greater than 1, a typical signature of CM. Based on these data, multiexciton yields are 48% and 75% for the undoped and doped samples, respectively.
