First-principles studies of the structural and electronic properties of poly-para-phenylene vinylene (2004)
Journal Article
Zheng, G., Clark, S., Brand, S., & Abram, R. (2004). First-principles studies of the structural and electronic properties of poly-para-phenylene vinylene. Journal of Physics: Condensed Matter, 16(47), 8609-8620. https://doi.org/10.1088/0953-8984/16/47/013

We present first-principles investigations of the structural and electronic properties of PPV in both the isolated chain and the crystalline state. The calculations are mainly based on the local density approximation within density functional theory....

Calculation of flexoelectric coefficients for a nematic liquid crystal by atomistic simulation (2004)
Journal Article
Cheung, D., Clark, S., & Wilson, M. (2004). Calculation of flexoelectric coefficients for a nematic liquid crystal by atomistic simulation. The Journal of Chemical Physics, 121(18), 9131-9139. https://doi.org/10.1063/1.1802231

Equilibrium molecular dynamics calculations have been performed for the liquid crystal molecule n-4-(trans-4-n-pentylcyclohexyl)benzonitrile (PCH5) using a fully atomistic model. Simulation data have been obtained for a series of temperatures in the... Read More about Calculation of flexoelectric coefficients for a nematic liquid crystal by atomistic simulation.

Dielectric and vibrational properties of amino acids (2004)
Journal Article
Tulip, P., & Clark, S. (2004). Dielectric and vibrational properties of amino acids. The Journal of Chemical Physics, 121(11), 5201-5210. https://doi.org/10.1063/1.1781615

We calculate polarizabilitytensors and normal mode frequencies for the amino acids alanine, leucine, isoleucine, and valine using density functionalperturbation theory implemented within the plane wave pseudopotential framework. It is found that the... Read More about Dielectric and vibrational properties of amino acids.

Ab initio studies of strained wurtzite GaN surfaces (2004)
Journal Article
Timon, V., Brand, S., Clark, S., & Abram, R. (2004). Ab initio studies of strained wurtzite GaN surfaces. Journal of Physics: Condensed Matter, 16(4), 531-542. https://doi.org/10.1088/0953-8984/16/4/002

In GaN and other group III nitrides the considerable lattice mismatch with the substrates normally employed during growth, such as sapphire, 6H-SiC and ZnO, can lead to the presence of strain which may affect the surface properties. Here we have stud... Read More about Ab initio studies of strained wurtzite GaN surfaces.
