4D-STEM datasets from Ribet, S.M., Ophus, C., Reis, R.D. and Dravid, V.P "Defect contrast with 4D-STEM: Applications of virtual detectors and beam modification." (2022).
The files here are:
1. PbTiO3 with a 2 mrad convergence angle
2. graphene with an 8, 14, and 20 mrad convergence angle
本四维扫描透射电子显微镜(4D-STEM)数据集源自Ribet, S.M.、Ophus, C.、Reis, R.D.与Dravid, V.P.于2022年发表的研究论文《4D-STEM下的缺陷衬度:虚拟探测器与束流修饰的应用》(原英文标题:Defect contrast with 4D-STEM: Applications of virtual detectors and beam modification)。
本次提供的数据集文件包含以下两类样品:
1. 收敛角为2毫弧度(mrad)的钛酸铅(PbTiO₃)样品
2. 收敛角分别为8、14及20毫弧度的石墨烯样品
