We present a detailed investigation performed at low temperature (T < 50 K) concerning the exciton dynamics in GaN epilayers grown on c-plane sapphire substrates, focusing on the exciton formation and the transition from the nonthermal to the thermal regim ...
The aim of this project was to investigate and quantify the impact of certain early design decisions on the solar potential of a target building placed in an urban context. This was done through a parametric study based on the successive variation of speci ...
Thermonuclear fusion of light atoms is considered since decades as an unlimited, safe and reliable source of energy that could eventually replace classical sources based on fossile fuel or nuclear fuel. Fusion reactor technology and materials studies are i ...
Molecular dynamics simulations of collision cascades in pure tungsten are performed to assess the primary damage due to irradiation. For short-range interaction the universal potential is used [1], while for long-range interaction, three different embedded ...
Electrochemical replication of nanoporous membranes represents a facile approach towards the fabrication of nanostructures with tailored properties. By the template method we prepared multisegment nanowires with tailored structure. The first step of the pr ...
TID and displacement damage effects are studied for vertical and lateral power MOSFETs in five different technologies in view of the development of radiation-tolerant fully integrated DC-DC converters. Investigation is pushed to the very high level of radi ...
Molecular dynamics simulations of collision cascades in pure tungsten are performed to assess the primary damage due to irradiation. For short-range interaction the universal potential is used [J.F. Ziegler, J.P. Biersack, U. Littmark, The Stopping and Ran ...
We report on a study of the sensitivity of silicon MEMS to proton radiation and mitigation strategies. MEMS systems can degrade due to ionizing radiation (electron-hole pair creation) and non-ionizing radiation (displacement damage), such as electrons, tra ...

We propose an original approach called a "stencil-masked ion implantation process" for performing a spatially localized synthesis of a limited number of Si nanocrystals within a thin SiO2 layer. In this process, the SiO2 layer is irradiated with 1 keV sili ...
In fusion power reactors, the plasma facing and breeding-blanket components will suffer intense irradiation by 14MeV neutrons. These high-energy fusion neutrons will produce atomic displacement cascades and nuclear transmutation reactions inside the irradi ...
