Anomalous Raman signals in multilayer hexagonal boron nitride grown by chemical vapour deposition on metal foil catalysts.

Summary: Scientists use a special, super-thin material called hBN to protect other tiny materials used in electronics. When they tried growing this hBN material in a lab using a special mix of iron and nickel metals, they found something surprising! When they tested the new material with a laser tool, it showed a strange new signal that had never been seen before. This new clue helps us understand how to make better materials for the computers and electronics of the future.
