This study demonstrates precise atomic-scale control over pore geometry in hexagonal boron nitride by manipulating the competition between electron beam sputtering and oxygen-mediated chemical etching. The ability to switch pore shapes from circular to triangular offers significant potential for advancing quantum technologies, alongside applications in filtration and DNA sequencing. While the material itself is not a quantum computer, this breakthrough in nanofabrication directly supports the development of interfaces and sensors critical for quantum systems.

Vienna team sculpts quantum atomic-scale pores in ‘white graphene’

Quantum ZeitgeistSeptember 11, 20263 min read

A University of Vienna team, led by Jani Kotakoski, precisely shaped atomic-scale pores in “white graphene” using electron irradiation and oxygen.

Researchers at the University of Vienna have demonstrated precise control over the shape of nanopores within hexagonal boron nitride at the atomic level. The team reports creating circular pores using electron irradiation in ultra-high vacuum, while the addition of even small amounts of oxygen yields triangular pores, a result building on electron irradiation techniques used to create triangular pores for nearly two decades. “We show for…
