Do high voltages affect the resonant frequency of a crystal? Honestly, we never thought about it, but [Joe] did and decided to risk his analyzer to find out. He started with some decidedly old-school ...

"Our goal was to overcome the challenges in realizing single-crystal perovskite devices", said Yusheng Lei, a nanoengineering graduate student and first author of the paper. "Our method is the first ...

Crystal polymorphism, the existence of different crystal structures for the same chemical compound, is a common phenomenon in chemistry. Many compounds are known to form multiple polymorphs depending ...

A research team at POSTECH has developed a method for synthesizing perovskite nanocrystals (PNCs), a next-generation semiconductor material, in a more uniform and efficient manner. This study is ...
