But it's not much help in figuring out a material's band structure, Qiu said, "which is what's necessary to really understand the properties of the material." Qiu and her team decided to focus on ...

The defining characteristic of topological materials is the presence of conducting surface states that are robust against external disturbances. This resilience is attributed to the non-trivial ...

In the experiments, the material serves a double function, Bilal explains, by being a perfect sound vacuum and wave amplifier at the same time. "A flat band in a band structure is a very special ...

Additionally, nanostructuring—altering the material's structure at the nanoscale—has emerged as a powerful method to engineer band gaps. Despite its potential, Band Gap Engineering faces challenges, ...
