This paper reports on the development of micromachined pillar arrays for the filtering of terahertz radiation. These pillar arrays are fabricated using ultraviolet based processing of thick SU8. This micromachining technique enables the array pattern... Read More about Artificial plasmonic materials for THz applications.

Screened Exchange Calculations of Semiconductor Band Structures (2005)
Presentation / Conference Contribution
Gibson, M. C., Clark, S. J., Brand, S., & Abram, R. A. (2005). Screened Exchange Calculations of Semiconductor Band Structures. In J. Menéndez, & C. G. Van de Walle (Eds.), . https://doi.org/10.1063/1.1994505

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...

The interaction of quantum well excitons with evanescent EM waves and the spectroscopy of waveguide polaritons (2005)
Presentation / Conference Contribution
Beggs, D., Kaliteevski, M., Brand, S., Abram, R., & Kavokin, A. (2005). The interaction of quantum well excitons with evanescent EM waves and the spectroscopy of waveguide polaritons. In J. Menéndez, & C. G. Van de Walle (Eds.), . https://doi.org/10.1063/1.1994526

A transfer matrix method has been used to calculate the dispersion relations of planar dielectric waveguides (WGs) containing quantum well (QW) excitons. It is found that WG polaritons are formed, whose dispersion displays the classic anti-crossing b...

First-principles calculations of 2×2 reconstructions of GaN surfaces (2005)
Presentation / Conference Contribution
Salinero, V., Gibson, M., Brand, S., Clark, S., & Abram, R. (2005). First-principles calculations of 2×2 reconstructions of GaN surfaces. In J. Menéndez, & C. G. Van de Walle (Eds.), . https://doi.org/10.1063/1.1994143

e GaN and other group III nitrides have great importance in a wide range of technological applications. Difficulty in growing good quality epitaxial GaN currently prevents the full technological potential of this material. The ab initio studies prese...
