| The data sets and the processing script (jupyter notebooks) are part of the publication "Wide field of view crystal orientation mapping of layered materials". The programming language used to process the data is written with python 3. The full manuscript can be found at: https://arxiv.org/abs/2011.01875 The experiments were performed on a JEOL JSM-5110 SEM at 20kV. The direct electron detector used was minipix camera of Advacam. In the notebooks, the data processing of the different 4D-STEM dataset is performed using the pixstem library and some self written packages. At the end of the processing, information on orientation, strain and multilayers of 2D materials (graphene, graphene oxide and MoS2) is retrieved. For the orientation mapping, the grain boundaries and average grain orientation are identified where due to the large field of view a large number of statistics on the grains is retrieved. Dataset 1: 512x512 scan of graphene with a field of view of 3600 um2 Dataset 2: 1024x1024 scan of graphene with a field of view of 0.112 mm2 Dataset 3: 512x512 scan of MoS2 with a field of view of 2.36 mm2 Dataset 4: 82x60 scan of graphene oxide, this is a small dataset and can be used to get familiar with the type of data processing. |
