Journal Article
Giblin, S., Terry, I., Clark, S., Prokscha, T., Prabhakaran, D., Boothroyd, A., …Leighton, C. (2005). Observation of magnetic excitons in LaCoO 3. European Physical Society Letters, 70(5), 677-683. https://doi.org/10.1209/epl/i2004-10519-4

An impurity-driven magnetic phase transition has been investigated in at temperatures below that of the thermally induced spin state transition of the ion. We have discovered a saturating component of the magnetisation, which we attribute to previous... Read More about Observation of magnetic excitons in LaCoO 3.

Theoretical adlayer surface morphology of wurtzite 2 × 2 reconstructions of the GaN (0001) surface (2005)
Journal Article
Timon, V., Brand, S., Clark, S., & Abram, R. (2005). Theoretical adlayer surface morphology of wurtzite 2 × 2 reconstructions of the GaN (0001) surface. Journal of Physics: Condensed Matter, 17(1), 17-26. https://doi.org/10.1088/0953-8984/17/1/002

In the first-principles calculations presented here we employ a density functional formalism using a pseudopotential plane-wave basis set in order to obtain the minimum energy configurations of various GaN(0001) 2 × 2 surfaces involving N atoms. The... Read More about Theoretical adlayer surface morphology of wurtzite 2 × 2 reconstructions of the GaN (0001) surface.

Screened Exchange Calculations of Semiconductor Band Structures (2005)
Presentation / Conference Contribution
Gibson, M. C., Clark, S. J., Brand, S., & Abram, R. A. (2004, July). Screened Exchange Calculations of Semiconductor Band Structures. Presented at 27th International Conference on the Physics of Semiconductors : ICPS-27., Flagstaff, Arizona

We have calculated the band structures of several group IV and III-V semiconductors from first principles. The technique we have employed is the screened exchange method, which is an extension of the commonly used Kohn-Sham density functional theory...
