Passive memristor synaptic circuits with multiple timing dependent plasticity mechanisms (2018)
Journal Article
Šuch, O., Klimo, M., Kemp, N. T., & Škvarek, O. (2018). Passive memristor synaptic circuits with multiple timing dependent plasticity mechanisms. AEÜ - International Journal of Electronics and Communications / Archiv für Elektronik und Übertragungstechnik, 96, 252-259. https://doi.org/10.1016/j.aeue.2018.09.025

Adaptation of synaptic strength is central to memory and learning in biological systems, enabling important high-level processes such as the ability of animals to respond to a changing environment. Memristor devices are a promising new, nanoscale tec... Read More about Passive memristor synaptic circuits with multiple timing dependent plasticity mechanisms.

Lyotropic 'hairy' TiO2 nanorods (2018)
Journal Article
Cheng, F., Verrelli, E., Alharthi, F. A., Kelly, S. M., O'Neill, M., Kemp, N. T., …Anthopoulos, T. (2019). Lyotropic 'hairy' TiO2 nanorods. Nanoscale advances, 1(1), 254-264. https://doi.org/10.1039/c8na00054a

We report the synthesis of the first stable, solution-processable and photocrosslinkable hybrid organic/inorganic titanium dioxide nanorods as ‘hairy rods’ coated with phosphonate ligands with photoreactive coumarin groups located in a terminal posit...

Method to reduce the formation of crystallites in ZnO nanorod thin-films grown via ultra-fast microwave heating (2018)
Journal Article
Gray, R. J., Jaafar, A. H., Verrelli, E., & Kemp, N. T. (2018). Method to reduce the formation of crystallites in ZnO nanorod thin-films grown via ultra-fast microwave heating. Thin solid films, 662, 116-122. https://doi.org/10.1016/j.tsf.2018.07.034

© 2018 This paper discusses the nucleation and growth mechanisms of ZnO nanorod thin-films and larger sized crystallites that form within the solution and on surfaces during an ultra-fast microwave heating growth process. In particular, the work focu... Read More about Method to reduce the formation of crystallites in ZnO nanorod thin-films grown via ultra-fast microwave heating.

An Optically-Programmable Absorbing Metasurface (2018)
Journal Article
Kossifos, K. M., Antoniades, M. A., Georgiou, J., Jaafar, A. H., & Kemp, N. T. (2018). An Optically-Programmable Absorbing Metasurface. IEEE International Symposium on Circuits and Systems, 2018-May, https://doi.org/10.1109/ISCAS.2018.8351874

A tunable metasurface absorber is presented in this work using an optically-programmable capacitor as the tuning element. The tuning element does not employ conventional semiconductor technologies to operate but rather a bases its tuning by changing... Read More about An Optically-Programmable Absorbing Metasurface.

Chua mem-components for adaptive RF metamaterials (2018)
Journal Article
Georgiou, J., Kossifos, K. M., Antoniades, M. A., Jaafar, A., & Kemp, N. T. (2018). Chua mem-components for adaptive RF metamaterials. IEEE International Symposium on Circuits and Systems, 2018-May, https://doi.org/10.1109/ISCAS.2018.8351852

Chua's mem-components are ideal for creating adaptive metasurfaces for manipulating EM waves given that they hold their state without external biases. In this paper, we propose a generic adaptive reactive element that is in fact a memcapacitor/memind... Read More about Chua mem-components for adaptive RF metamaterials.
