Researchers at ARCNL have found a way to detect nanostructures buried under many layers of opaque material using high-frequency sound waves induced by light. Their findings could have applications in the semiconductor manufacturing industry, such as wafer alignment. The researchers also revealed interesting new phenomena in photo-acoustics that have not been investigated before. Their results are published in Physical Review Applied. First author Stephen Edward successfully defended his Ph.D. on this subject on 18 June at the University of Amsterdam.
