Legal and illegal export of cultural heritage artefacts from developing countries: Protection of cultural heritage in South Africa
Autor: Jen Snowball, Alan Collins, Craig Bickerton
Publikováno v: Cogent Social Sciences, Vol 9, Iss 1 (2023)
Cultural heritage is an important part of the capital of developing countries that can be leveraged for sustainable development. However, it also needs protection as the rise in the illegal trade of cultural artefacts shows. South Africa as an exampl

Autor: Piers Andrew, Chris Bower, Surama Malik, Joseph Bottomley, Alexander Bessonov, Rushton Ashley, Alan Colli, Yinglin Liu, Mark G. Allen, Sami Kallioinen, Martti Voutilainen, Tapani Ryhänen, Ivonne Medina-Salazar
Publikováno v: ACS nano. 11(6)
Colloidal quantum dots (QDs) combined with a graphene charge transducer promise to provide a photoconducting platform with high quantum efficiency and large intrinsic gain, yet compatible with cost-efficient polymer substrates. The response time in t

Graphene is used as the thinnest possible spacer between gold nanoparticles and a gold substrate. This creates a robust, repeatable, and stable subnanometer gap for massive plasmonic field enhancements. White light spectroscopy of single 80 nm gold n

There is a growing number of applications demanding highly sensitive photodetectors in the mid-infrared. Thermal photodetectors, such as bolometers, have emerged as the technology of choice, because they do not need cooling. The performance of a bolo

The morphology of silicon nanowire samples: A Raman study
Autor: H. Scheel, Andrea C. Ferrari, Alan Colli, Mirco Cantoro, Christian Thomsen, Sevak Khachadorian
Publikováno v: physica status solidi (b). 246:2809-2812
Raman spectra of silicon nanowires (SiNWs) are studied as a function of laser excitation power and temperature. With increase in temperature and power a red-shift of the SiNWs first order optical mode is observed. At ambient conditions, the Raman shi

Fabrication of graphene nanoribbons via nanowire lithography
Autor: A. Fasoli, Alan Colli, Antonio Lombardo, Andrea C. Ferrari
Publikováno v: physica status solidi (b). 246:2514-2517
Graphene nanoribbons (GNRs) are the counterpart of nanotubes in graphene nanoelectronics. The search for a cheap, parallel, and deterministic technique for practical implementation of these structures is still open. Nanowire lithography (NWL) consist

Silicon nanowire optical Raman line shapes at cryogenic and elevated temperatures

Publikováno v: physica status solidi (b). 245:2090-2093
We report the Raman spectra of silicon nanowires (SiNWs) in a wide temperature range, between 2 K and 850 K. At room temperature we find a strong influence on the spectrum from applied laser excitation powers. These effects can be attributed a laser

Ion Beam Doping of Silicon Nanowires
Autor: Simone Pisana, Alan Colli, S. Piscanec, Andrea C. Ferrari, Carsten Ronning, A. Fasoli
Publikováno v: Nano Letters. 8:2188-2193
We demonstrate n- and p-type field-effect transistors based on Si nanowires (SiNWs) implanted with P and B at fluences as high as 10(15) cm (-2). Contrary to what would happen in bulk Si for similar fluences, in SiNWs this only induces a limited amou
