WebApr 19, 2024 · In 2012, I developed atomic electron tomography (AET) for 3D structure determination of crystal defects and disordered materials. Over the last ten years, AET has been applied to image grain boundaries, anti-phase boundaries, stacking faults, dislocations, point defects, chemical order/disorder, and strain tensors with unprecedented 3D detail. Web2 days ago · The Br-I ordered all-inorganic halide perovskite CsPbBr2I is first obtained, induced by an unprecedented Br-I ordered intermediate PbBrI-(DMSO)2. The unique Br-I layered-alternating structure offers a distinctive anisotropy in charge transport by which the CsPbBr2I single crystal realizes a record carrier mobility of 2,574 cm2 V−1 s−1, exhibits …
