Scientists Create 3D Material That Conducts Electricity Like Graphene But Won't Break

A Major Step Beyond Graphene's Limitations

Graphene has been hailed as a wonder material since its discovery, celebrated for being incredibly strong, lightweight, and an exceptional conductor of electricity. It has found applications across electronics, aerospace, and medical technologies. However, there has always been a significant catch: graphene's two-dimensional structure makes it mechanically fragile and extremely difficult to deploy in demanding real-world environments or at industrial scale.

The Liverpool Discovery

Now, scientists at the University of Liverpool have identified a three-dimensional material that could change everything. In research published in the journal Matter on Tuesday, the team revealed that a compound called hafnium stannide can mimic graphene's remarkably fast electron flow despite having a fully three-dimensional atomic structure.

The research was jointly led by Doctor Jonathan Alaria from the Physics department and Professor Matthew Rosseinsky from Chemistry. They found that hafnium stannide contains honeycomb layers arranged in three dimensions with a special chiral stacking pattern similar to the twist found in DNA. This unique arrangement preserves the electronic behaviour typically seen only in two-dimensional materials.

Why This Matters for Computing

The material also hosts what physicists call Weyl pointsÔÇöunusual features in the electronic structure that dramatically enhance how easily electrons can move through the material. This makes hafnium stannide particularly attractive for next-generation, low-energy logic and spintronic devices that are central to future computing technologies.

As global energy consumption from data centres and computing infrastructure continues to climb, materials that enable more efficient electron transport could prove crucial for developing greener computing solutions.

Part of a Larger Initiative

The research forms part of a broader eight point six million pound initiative called Digital Navigation of Chemical Space for Function, which combines physical science with artificial intelligence and machine learning to discover new functional materials. The work involved collaboration with the Max Planck Institute in Dresden and AGH University of Krakow.
