Mechanistic Studies as a Tool for the Design of Copper‐Based Heterostructures

Under control of X-rays, the composition of copper heterostructures can be precisely tuned on a scale spanning from that of an individual heterojunction to the macroscale. This is achieved via in situ powder X-ray diffraction studies and facilitates their technological application.
