Rare-Earth Nitrides: Fundamental Advances and Applications in Cryogenic Electronics
W. F. Holmes-Hewett, J. D. Miller, H. G. Ahmad +2
Driven by the pursuit of high-performance electronic devices, research into novel materials with properties appropriate for cryogenic applications has unveiled the exceptional prop…
Conductivity of high-mobility epitaxial GdN
Edward X. M. Trewick, B. J. Ruck, W. F. Holmes-Hewett +1
We report electron transport studies of a (001) GdN film grown on the square net presented by the (001) surface of LaAlO3, motivated by recent advances in epitaxial thin-film growt…
Unconventional superconductivity and quantum criticality in SmN
W. F. Holmes-Hewett, K. Van Koughnet, J. D. Miller +3
Nitrogen vacancy doped SmN is a semiconductor which lies in the intermediary between insulating-ferromagnetic SmN and metallic-anti-ferromagnetic Sm. The dopant electrons r…
Following enhanced Sm spin projection in GdSmN
J. D. Miller, J. F. McNulty, B. J. Ruck +6
The rare-earth nitrides form a series of structurally simple ferromagnetic semiconductors, a rare class of both fundamental interest and application potential. Within t…
In-situ monitoring of room temperature reactions of lanthanides with nitrogen and hydrogen at low pressures
Jay R. Chan, H. Joe Trodahl, Denis Lefebvre +2
The dissociative chemisorption of molecular nitrogen on clean lanthanide surfaces at ambient temperature and low pressure is explored. In-situ conductance measurements track the co…
4f Conduction in the Magnetic Semiconductor NdN
W. F. Holmes-Hewett, R. G. Buckley, B. J. Ruck +2
We report the growth of films of the intrinsic ferromagnetic semiconductor NdN, and an investigation of their optical and transport properties. There is clear evidence of a strong…
