Depuis une vingtaine d’années en Suisse, le « taux de séparation scolaire », c’est-à-dire le nombre d’élèves scolarisés en classe spéciale ou en établissement de pédagogie spécialisée, ne cesse de diminuer. Une partie des classes spéciales ont fermé et les élèves ont été réintégrés en classe régulière. Une autre partie de ces classes ont été transformées en dispositifs plus flexibles favorisant une plus grande mobilité des élèves. Deux recherches menées auprès d’élèves bénéficiant de mesures de pédagogie spécialisée dans le canton de Vaud montrent qu’une partie de ces élèves restent dans les f

L’année 2015 marque un tournant dans la mobilité de demandeurs d’asile et réfugiés au sein de l’Europe, en matière de volume des arrivées, de reconfiguration des routes et de direction des flux. L’analyse des premières données statistiques et ethnographiques du projet AMORE (Afghan Europeans. The Invention of a Mobility Regime) portant sur les circulations des populations afghanes en Europe permet d’identifier l’existence de « couloirs migratoires » tout en invitant à prendre des précautions dans l’interprétation des statistiques.

Ces couloirs se superposent au niveau des pratiques autant qu’au niveau des réseaux et des ressources. Les cinq points plus concrets qu’on va aborder ici sont la circulation de l’argent, le rôle des médiateurs culturels des migrants, la question du confort et la façon d’inves

Abstract:
A physics based device simulator for detailed numerical analysis of 4H-SiC MOSFETs with an advanced mobility model that accounts for the effects of bulk and surface phonons, surface roughness and Coulomb scattering by occupied interface traps and fixed oxide charges, has been developed. A first principles quasi-2D Coulomb scattering mobility model specifically for SiC MOSFETs has been formulated. Using this, we have been able to extract the interface trap density of states profile for 4H-SiC MOSFETs and have shown that at room temperature, Coulomb scattering controls the total mobility close t

Abstract:
In prior work we have proposed a mobility model for describing the mobility degradation observed in SiC MOSFET devices, suitable for being implemented into a commercial simulator, including Coulomb scattering effects at interface traps. In this paper, the effect of temperature and doping on the channel mobility has been modelled. The computation results suggest that the Coulomb scattering at charged interface traps is the dominant degradation mechanism. Simulations also show that a temperature increase implies an improvement in field-effect mobility since the inversion channel concentration in

The gate–channel electron density and low-field mobility were obtained by measuring the capacitance–voltage characteristics and current–voltage characteristics. After proton irradiation, the gate–channel low-field electron mobility of the AlGaN/GaN HEMT with a 30 μm gate–drain distance increases and that with a 10 μm gate–drain distance decreases.

A high field-effect mobility peak (50 cm2/Vs) has been extracted in (0001) Si face 4HSiC MOSFETs with oxidized Ta2Si (O-Ta2Si) high-k dielectric (k~20) as gate insulator, with their gates in the strong inversion regime. The interface state density (Dit) has not been particularly reduced in O-Ta2Si capacitors. This anomalous mobility enhancement is explained in terms of Coulomb scattering reduction and quantified using a physical model based on the Lombardi mobility model. The anomalous mobility increase is closely related to the leakage current, and also to the gate breakdown mechanism. We pro

Main scattering mechanisms affecting electron transport in MOS/SOI devices are considered within the quantum-mechanical approach. Electron mobility components (i.e., phonon, Coulomb and interface roughness limited mobilities) are calculated for ultrathin symmetrical DG SOI transistor, employing the relaxation time approximation, and the effective electron mobility is obtained showing possible mobility increase relative to the conventional MOSFET in the range of the active semiconductor layer thickness of about 3 nm.

Abstract In a conventional metal such as Cu, an abnormal distribution of electronic charge will vanish very quickly indeed (in less than about 1 picosec). The reason for this rapid dispersion is of course the strong Coulomb forces between 158 electrons spaced by distances ˜ 0.3 nm and the electrons’ high mobility. However, in semiconductors, we have the possibility of the simultaneous existence of holes and electrons (see Section 9.3.1). If we inject an excess of minority carriers (say holes) into a semiconductor, then the majority carriers (say electrons) will move to the region containing th
