Vibrational properties of rare-earth nitrides: Raman spectra and theory (2009)
Granville, S., Meyer, C., Preston, A.R.H., Trodahl, H.J., Paudel, T.R., Lambrecht, W.R.L.
Raman spectra are presented for the rare-earth nitrides SmN, GdN, DyN, ErN, and LuN measured with 633 and 514 nm excitation wavelengths and at temperatures above and below the Curie temperature....
Ferromagnetic redshift of the optical gap in GdN (2007)
Trodahl, H. J., Preston, A. R. H., Zhong, J., Ruck, B. J., Strickland, N., Mitra, C., ...
We report measurements of the optical gap in a GdN film at temperatures from 300 to 6K, covering both the paramagnetic and ferromagnetic phases. The gap is 1.31eV in the paramagnetic phase and...
Comparison between experiment and calculated band structures for DyN and SmN (2007)
Preston, A. R. H., Granville, S., Housden, D. H., Ludbrook, B., Ruck, B. J., Trodahl, H. J., ...
We investigate the electronic band structure of two of the rare-earth nitrides, DyN and SmN. Resistivity measurements imply that both materials have a semiconducting ground state, and both show...

Recent Advances in Atomic-Scale Spin-Polarized Scanning. (2005)
Smith, A. R., Yang, R., Yang, H. Q., Dick, A., Neugebauer, J., Lambrecht, W. R. L.
A Comparison of the Wurtzite and Zincblende Band Structures for SiC, AlN and GaN. (1998)
Lambrecht, W. R. L., Segall, B.
Total energy and band structure results of linear-muffin-tin orbital calculations within the atomic-sphere-approximation are presented for SiC, GaN and AlN in the zincblende and the wurtzite...
Spin-dependent resonant tunneling through semimetallic ErAs quantum wells (1995)
Petukhov, A. G., Lambrecht, W. R. L., Segall, B.
Resonant tunneling through semimetallic ErAs quantum wells embedded in GaAs structures with AlAs barriers was recently found to exhibit an intriguing behavior in magnetic fields which is explained in...
