Synchrotron XRD data on plastic strain-induced phase transformations in Si
Silicon is an important electronic material, and this study reveals its various plastic strain-induced piezoelectric phenomena. The study uses synchrotron X-ray diffraction (XRD) in axial geometry to investigate the plastic strain-induced phase transformation phenomena in silicon (Si) with different particle sizes. Plastic compression experiments were conducted inside a diamond anvil cell (DAC) for micron-sized, 100 nm, and 30 nm Si. The XRD patterns were collected along the culet diameter with a step size of 8 μm for the micron sample and 10 μm for the 100 nm and 30 nm samples. The dataset is organized into six major folders which contain .tif, .jpg, .txt, .xy, .chi, .log, .poni, .npz, and .mask files.
