title: Replication Data for "Dynamics of purification in Cu2O"

description: Replication Data for: "Dynamics of purification in Cu2O"&lt;br&gt;
&lt;br&gt;
Raw and processed data as well as fit results shown in "Dynamics of purification in Cu2O". &lt;br&gt;
Rydberg excitons in the semiconductor Cu2O were shown to be highly efficient in neutralizing and screening charged impurities, which is referred to as purification. 
We investigate the dynamics of this process, using a pump - probe experiment with improved temporal resolution of 15 ns. We analyze the transient absorption of Rydberg excitons and uncover five different physical mechanism that influence it. Further, we compare the impact of excitons and an electron-hole plasma on the purification process. &lt;br&gt;
A thorough discussion of the analysis is given in the related publication.&lt;br&gt;
&lt;br&gt;
Files contain the data shown in figures 2-6 of the publication in ASCII format. No special software needed.&lt;br&gt;
The following files include time-resolved transients for a probe laser resonant with the 10P exciton and a pump laser at 16P exciton at varying probe laser powers. &lt;br&gt;
