Electrical Characterisation of Ultra-thin SAM Structures
The way of reduction of metal oxyde semiconductor (MOS) structures is going
to reach limitations and new devices have to be explored as an alternative to
MOS technology. Molecular electronic and more particularly
self-assembly-molecular technique on silicon substrate gives interesting
results as seen in the literature. We are going to study n-alkyltrichlorosilane
grafting on oxidised silicon, characterise it macroscopically with ellipsometer
and goniometry measurements, and down to microscopic scale with atomic force
microscopy. Once the uniformity of the monolayer is verified (roughness of few
Angstr\"oms) we have tested a sputtering method deposition to form aluminium
dots onto the surface. Also metal-insulator-semiconductor diodes are tested
measuring both leakage current between gate and substrate and
capacitance-voltage. The sputtering method deposition can be improved in order
to decrease the gate leakage current and we would like to test another
evaporation method. Further application we want to study is gas sensors using
conjugated organic films or synthetic polymers and concerns the drift current
with gas absorption.Comment: Submitted on behalf of TIMA Editions

Share Opportunity Sets and Cooperative Games
In many share problems there is a priori given a natural set of possible divisions to solve the sharing problem.Cooperative games related to such share sets are introduced, which may be helpful in solving share problems.Relations between properties of share sets and properties of games are investigated.The average lexicographic value for share sets and for cooperative games is studied.cooperative games;bankruptcy games;average lexicographic value;opportunity sets

Satellite networking integration in the 5G ecosystem: Research trends and open challenges
The envisioned 5G ecosystem will be composed of heterogeneous networks based on different technologies and communication means, including satellite communication networks. The latter can help increase the capabilities of terrestrial networks, especially in terms of higher coverage, reliability, and availability, contributing to the achievement of some of the 5G KPIs. However, technological changes are not immediate. Many current satellite communication networks are based on proprietary hardware, which hinders the integration with future 5G terrestrial networks as well as the adoption of new protocols and algorithms. On the other hand, the two main paradigms that are emerging in the networking scenario \u2014 software defined networking (SDN) and network functions virtualization \u2014 can change this perspective. In this respect, this article presents first an overview of the main research works in the field of SDN satellite networks in order to understand the already proposed solutions. Then some open challenges are described in light of the network slicing concept by 5G virtualization, along with a possible roadmap including different network virtualization levels. The remaining unsolved problems are related to the development and deployment of a complete integration of satellite components in the 5G ecosystem
