Hybrid FIB milling strategy for the fabrication of plasmonic nanostructures on semiconductor substrates (2011)
Journal Article
Einsle, J. F., Bouillard, J. S., Dickson, W., & Zayats, A. V. (2011). Hybrid FIB milling strategy for the fabrication of plasmonic nanostructures on semiconductor substrates. Nanoscale Research Letters, 6(1), Article 572. https://doi.org/10.1186/1556-276X-6-572

The optical properties of plasmonic semiconductor devices fabricated by focused ion beam (FIB) milling deteriorate because of the amorphisation of the semiconductor substrate. This study explores the effects of combining traditional 30 kV FIB milling... Read More about Hybrid FIB milling strategy for the fabrication of plasmonic nanostructures on semiconductor substrates.

Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 kms-1, and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/d galaxy. We show that our simulated galaxy has no classic... Read More about Hierarchical formation of bulgeless galaxies - II. Redistribution of angular momentum via galactic fountains: Bulgeless discs II.

We study the thiophene-based oligomer poly[2,7-(9,9-bis(2′-ethylhexyl)fluorene)-alt-2,5-terthiophene] (PF3T) in solution and when dispersed at low concentration into a polynorbornene matrix. We find that at high concentration in solution the 0–0 elec... Read More about Spectroscopy and single-molecule emission of a fluorene-terthiophene oligomer.
