μ-ATOMS aims to discover the underlying science principles determining the ordering of atoms in semiconductor alloys, enabling a breakthrough in the synthesis for semiconductor properties and structures. This is inspired by much of the science that this team recently uncovered on novel Group IV alloy semiconductor materials that demonstrate the short-range order (SRO) of Ge and Sn atoms on the periodic lattice of GeSn, has a very large effect on the energy band gap.

This discovery presented an exciting hypothesis: A new “Synthesis by Design” is possible by only manipulating the order of atoms in alloys, to fabricate material properties. Researching and developing the missing knowledge base essential to understanding the different aspects of SRO in Group-IV alloys is the key challenge of μ-ATOMS.

Vision, approach, and science of u-Atoms EFRC

The outcome of this EFRC is a knowledge base that can enable a scaled-up, reliable, and cost-effective sequence of operations for manufacturing semiconductor structures and devices from the bottom-up. μ-ATOMS is expected to achieve new science of deterministic positioning, with a codesign purpose to utilize the spatial arrangements of atoms to fabricate novel heterostructures and graded morphologies using a single material, purposely ordered.
