AET has previously been used to image 3D crystal defects (such as dislocations, stacking faults, grain boundaries, chemical order/disorder and point defects) in materials at the single-atom level.

Here we discover that mechanical deformations provide a route to switching thermodynamic stability between a semiconducting and a metallic crystal structure in these monolayer materials.

nearly perfect cube of silver onto a hard target turns its single-crystal microstructure into a gradient-nano-grained (GNG) structure. Scientists at Rice University are smashing metallic micro ...

The researchers are the first to observe metallic lines in a perovskite ... composition of elements as the host crystal, the changes in electronic band structure at the dislocation core, due ...

Unfortunately, typical metallic luster materials cause environmental ... The team attributed this to the unique crystal structure of DS-DA1 with two coexisting assembled states, revealing that ...

A new study by Professor Tao Sun tracks the evolution of crystallographic defects in real time during metal additive manufacturing.
