Does the boson peak survive in an ultrathin oxide glass?
D. L. Cortie, M. J. Cyster, J. S. Smith +7
Bulk glasses exhibit extra vibrational modes at low energies, known as the boson peak. The microscopic dynamics in nanoscale alumina impact the performance of qubits and other supe…

The effect of atomic structure on the electrical response of aluminium oxide tunnel junctions
M. J. Cyster, J. S. Smith, J. A. Vaitkus +3
Many nanoelectronic devices rely on thin dielectric barriers through which electrons tunnel. For instance, aluminium oxide barriers are used as Josephson junctions in superconducti…
