New method enables programming the growth of semiconductor crystals — Nature
Nature reported on an approach using an etching flux that makes it possible to control where the growth of crystals of two-dimensional semiconductors begins. The method confines the area where a crystal nucleus forms and enables spatially programmed growth of large single crystals of semiconductor material.
Controlling crystal nucleation
Semiconductor crystals grow from very small nuclei. It is difficult to determine precisely where they form, although the position of such a nucleus can affect the properties of the crystal.

The new approach is intended to confine the location where a nucleus forms. This makes it possible to control the spatial position of the beginning of crystal growth.
Research on two-dimensional semiconductors
The Nature article in the Research Briefings section dated October 7, 2026, summarizes a study by Pak and co-authors. The work is titled “Spatially deterministic nucleation of 2D semiconductors by etching flux” and concerns spatially deterministic nucleation of two-dimensional semiconductors using an etching flux.
