Precession-assisted 4D-STEM datasets of Sb2S3 thin film and in situ TEM observations

Sb2S3_NoPrec_Ort2_DPs.hspy: nano-beam 4D-STEM dataset of Sb2S3 using TESCAN Tensor without precession.Sb2S3_Prec1deg_Ort2_DPs.hspy:nano-beam 4D-STEM dataset of Sb2S3 using TESCAN Tensor with precession (1 degree).In situ STEM observations Here, the ".emd" files are raw Velox file with 4 simultaneous imaging channels, and the ".mrc" file is exported MRC file of the beter contrast channel of ADF-STEM). “1520 STEM HAADF-DF-I-DF-O-BF ADF”: STEM-ADF movie showing phase transformation of Sb2S3 during an in situ observation at temperature between 240 and 245⁰C. Data acquired at 628 ms/frame. The temperature reached 240⁰C at frame #960, and very slowly raised to 250⁰C at frame #1130 and hold to the last frame #1682. “1545 STEM HAADF-DF-I-DF-O-BF ADF”: STEM-ADF movie showing degradation of Sb2S3 during an in situ observation at a temperature of 350⁰C. Data acquired at 492 ms/frame. The temperature reached 290⁰C at frame #60, raised to 350⁰C at frame #200 and hold there until the end of movie. “1038 STEM HAADF-DF4-DF2-BF DF4.mrc”: STEM-ADF movie showing nucleation and growth of Sb2S3 from the a-Sb2S3/ZnS sample during an in situ observation when the temperature was kept at 250⁰C. Data acquired at 400 ms/frame.
