Episode 122: 100 Years of Point Defects

What do a ruby, a transistor, a blue LED, and a quantum sensor have in common? They all work because of point defects. To celebrate the 100th anniversary of the point defect, we sit down with Dr. Mike Scarpulla, a professor at the University of Utah and co-editor of a special MRS Bulletin issue on the topic. We explore how a single missing or misplaced atom can change everything. From the history, to the measurement techniques that let us finally see what Frenkel could only imagine, and where defect engineering is headed next.
