Negative differential resistance associated with hot phonons (2012)
Journal Article
Dyson, A., & Ridley, B. K. (2012). Negative differential resistance associated with hot phonons. Journal of applied physics, 112(6), 063707. https://doi.org/10.1063/1.4754012

We predict the existence of a hot-phonon negative differential resistance (NDR) in GaN. We show that this is a consequence of a wave-vector dependence of lifetime caused by the effect of coupled plasmon-phonons. Anti-screened long-wavelength modes ha...

Low-temperature plasmonics of metallic nanostructures (2012)
Journal Article
Bouillard, J. S. G., Dickson, W., O’Connor, D. P., Wurtz, G. A., & Zayats, A. V. (2012). Low-temperature plasmonics of metallic nanostructures. Nano Letters, 12(3), 1561-1565. https://doi.org/10.1021/nl204420s

The requirements for spatial and temporal manipulation of electromagnetic fields on the nanoscale have recently resulted in an ever-increasing use of plasmonics for achieving various functionalities with superior performance to those available from c...

Ultrafast heating as a sufficient stimulus for magnetization reversal in a ferrimagnet (2012)
Journal Article
Ostler, T. A., Barker, J., Evans, R. F., Chantrell, R. W., Atxitia, U., Chubykalo-Fesenko, O., …Kimel, A. V. (2012). Ultrafast heating as a sufficient stimulus for magnetization reversal in a ferrimagnet. Nature communications, 3, Article 666. https://doi.org/10.1038/ncomms1666

The question of how, and how fast, magnetization can be reversed is a topic of great practical interest for the manipulation and storage of magnetic information. It is generally accepted that magnetization reversal should be driven by a stimulus repr... Read More about Ultrafast heating as a sufficient stimulus for magnetization reversal in a ferrimagnet.

Effect of particulate contamination on adhesive ability and repellence in two species of ant (Hymenoptera; Formicidae) (2012)
Journal Article
Anyon, M. J., Orchard, M. J., Buzza, D. M. A., Humphries, S., & Kohonen, M. M. (2012). Effect of particulate contamination on adhesive ability and repellence in two species of ant (Hymenoptera; Formicidae). The journal of experimental biology, 215(4), 605-616. https://doi.org/10.1242/jeb.063578

Tarsal adhesive pads are crucial for the ability of insects to traverse their natural environment. Previous studies have demonstrated that for both hairy and smooth adhesive pads, significant reduction in adhesion can occur because of contamination o...
