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…
Vertical transport and tunnelling in rare-earth nitride heterostructures
Jackson D. Miller, Felicia H. Ullstad, H. Joe Trodahl +2
We report an investigation of the ferromagnetic semiconductor rare earth nitrides (RENs) for their potential for cryogenic-temperature electronics and spintronics application. We h…
Optical Spectroscopy of SmN: Evidence for 4f Transport
W. F. Holmes-Hewett, R. G. Buckley, B. J. Ruck +2
The rare-earth nitride ferromagnetic semiconductors owe their varying magnetic properties to the progressive filling of 4f shell across the series. Recent electrical transport meas…
Breaking molecular nitrogen under mild conditions with an atomically clean lanthanide surface
Felicia Ullstad, Gabriel Bioletti, Jay Chan +5
A route to break molecular nitrogen (N2) under mild conditions is demonstrated by N2 gas cracking on, and incorporation into, lanthanide films. Successful growth of lanthanide nitr…
AlN interlayer to improve the epitaxial growth of SmN on GaN (0001)
Stéphane Vézian, Benjamin Damilano, Franck Natali +2
An in situ study of the epitaxial growth of SmN thin films on Ga-polar GaN (0001)templates by molecular beam epitaxy is reported. Using X-ray photoelectron spectroscopy we found th…
Superconductivity in the ferromagnetic semiconductor SmN
E. -M. Anton, S. Granville, A. Engel +8
The discovery of materials that simultaneously host different phases of matter has often initially confounded, but ultimately enhanced, our basic understanding of the coexisting ty…
Highly resistive epitaxial Mg-doped GdN thin films
C. -M. Lee, H. Warring, S. Vézian +7
We report the growth by molecular beam epitaxy of highly resistive GdN, using intentional doping with magnesium. Mg-doped GdN layers with resistivities of 1000 Ω.cm and carrier con…
Electric field and photo-excited control of the carrier concentration in GdN
Harry Warring, B. J. Ruck, H. J. Trodahl +1
We present both electric-field and photo-excited control of the carrier concentration in GdN. There is no evidence in the results of a carrier-mediated contribution to the Gd-Gd ex…
The role of magnetic polarons in ferromagnetic GdN
Franck Natali, Ben Ruck, Joe Trodahl +6
We report an interplay between magnetism and charge transport in the ferromagnetic semiconductor GdN, pointing to the formation of magnetic polarons centred on nitrogen vacancies.…
Rare-earth mononitrides
Franck Natali, Ben J. Ruck, Natalie O. V. Plank +4
When the rare earth mononitrides (RENs) first burst onto the scientific scene in the middle of last century, there were feverish dreams that their strong magnetic moment would affo…
Epitaxial ferromagnetic semiconductor GdN thin films on Si substrate
F. Natali, N. O. V. Plank, B. J. Ruck +4
