Thermoelectric sample Cu2MnGeS4 - M282 - Enargite phase

M282-Enargite

The following submission contains the data collection and processing of datasets for the sample M282, with composition Cu2MnGeS4 – Epidote phase, in the framework of the publication: Pavan Kumar, V., Passuti, S., Zhang, B., Fujii, S., Yoshizawa, K., Boullay, P., ... & Guilmeau, E. (2022). Engineering Transport Properties in Interconnected Enargite‐Stannite Type Cu2+ xMn1− xGeS4 Nanocomposites. Angewandte Chemie International Edition, 61(49), e202210600.

A single crystal was identified, and precession data acquisition techniques were used to collect datasets on the same crystal. The data sets were processed with PETS2 software. The table below summarizes the data collection parameters for the data sets. The following data is also included as a text file in the data folder.
