Low temperature characterization of 14nm FDSOI CMOS devices

Abstract: A detailed characterization of low temperature operation of n and p MOS devices from 14nm FDSOI CMOS technology has been conducted. The transfer characteristics measured between 77K and 300K exhibit very good performance for effective gate lengths down 15nm, emphasizing the very good control of short channel effects and subthreshold behavior. Moreover, the temperature dependence of the low field mobility clearly indicates that, for long devices, it is limited by phonon scatterings whereas, for sub 100nm gate lengths, the mobility is significantly degraded and almost independent with temperature. This feature is attributed to scattering by neutral defects, which are originated from source and drain process and extending over several tens of nm along the channel.

Tunisian date palm rachis used as an alternative source of fibres for papermaking applications

Abstract: Every year, significant amounts of date palm rachises are accumulated in Tunisia. The rational valorisation of this renewable resource is therefore imperative, in order to fulfil the sustainability approach. In this context, this work aims to study the potential use of date palm rachises as a raw material for papermaking and to compare it with other sources of lignocellulosic fibres, such as wood, non-wood species, and agricultural wastes. For this purpose, soda-anthraquinone pulping of date palm rachis was performed giving rise to a yield of 45% (w/w). This value is similar to that obtained by pulping non-wood materials and is higher than that corresponding to the pulping of agricultural residues. The resulting pulps were subsequently refined using a PFI mill refiner at 0, 500, 1500, and 3000 revolutions, screened through a 0.15 mm mesh size sieve and used to produce conventional handsheets. Both pulps and papers were fully characterized in terms of morphological, chemical and physical properties, according to commonly used standards. The physical properties of the prepared handsheets were very similar to those displayed by other papers made of common lignocellulosic fibres. Furthermore, the pulps exhibited a good drainability together with excellent mechanical properties of the ensuing papers. For these reasons, date palm rachises could be considered as a potential source of fibres for papermaking applications.
