A team of scientists led by Nanyang Technological University (NTU Singapore) and Rice University in the US, has uncovered the key to the outstanding toughness of hexagonal boron nitride (h-BN). It can withstand ten times the amount of force that graphene can, which is known as one of the toughest materials on Earth.

In their recent paper, A. J. H. Jones and S. Ulstrup et al. explore engineering properties of quantum materials by placing a singularity of the density of states near the Fermi energy. Using ebeam lithography for structuring and formation of electrical contacts, a device consisting of twisted bilayer graphene (twBG) on a stack of hBN and graphite was formed. The device was wire bonded to a chip package and introduced to the nanoARPES branch of the I05 beamline at the Diamond light source.

The Multiprobe prep is the latest addition to Scienta Omicron’s range of modular UHV system platforms. It serves as both a preparation chamber for a wide range of analytical systems, and as an independent UHV system compatible with the addition of the award-winning Variable Temperature SPM (model VT SPM-XA) housed in its own bolt-on chamber.
