Single Event Upsets Induced by Direct Ionization from Low-Energy Protons in Floating Gate Cells
2017
Floating gate cells in advanced NAND Flash memories, with single-level and multi-level cell architecture, were exposed to low-energy proton beams. The first experimental evidence of single event upsets by proton direct ionization in floating gate cells is reported. The dependence of the error rate versus proton energy is analyzed in a wide energy range. Proton direct ionization events are studied and energy loss in the overlayers is discussed. The threshold LET for floating gate errors in multi-level and single-level cell devices is modeled and technology scaling trends are analyzed, also discussing the impact of the particle track size. peerReviewed
Measurements of Low-Energy Protons using a Silicon Detector for Application to SEE Testing
2021
A silicon detector with a fast electronics chain is used for the dosimetry of protons in the range 0.5-5 MeV at the Centro Nacional de Aceleradores (CNA) 3 MV Tandem laboratory in Seville, Spain. In this configuration, measurements can be performed in pulsed mode, using a digitizer to record event-by-event proton energy depositions. The distributions of deposited energy were obtained thanks to a calibration with an alpha source. Measurements of flux and deposited energy are used to enable single event effect (SEE) testing on selected static random access memories (SRAMs).
Proton Direct Ionization in Sub-Micron Technologies : Test Methodologies and Modelling
2023
Two different low energy proton (LEP) test methods, one with quasi-monoenergetic and the other with very wide proton beam energy spectra, have been studied. The two test methodologies have been applied to devices that were suggested from prior heavy-ion tests to be sensitive to proton direct ionization (PDI). The advantages and disadvantages of the two test methods are discussed. The test method using quasi-monoenergetic beams requires device preparation and high energy resolution beams, but delivers results that can be interpreted directly and can be used in various soft error rate (SER) calculation methods. The other method, using a heavily degraded high energy proton beam, requires littl…
Associations between perceived parental psychological control and internalizing difficulties in emerging adulthood: the role of identity
2016
Our study investigated the associations among two expressions of perceived parental psychological control (dependency-oriented parental control [DPC] and achievement-oriented parental control [APC]), identity, and internalizing difficulties among college-attending emerging adults. In particular, our aim was to examine the potential role of identity in the pathways linking both DPC and APC to internalizing difficulties. Our participants included 495 Italian college students (49% males), between 19 and 28 years of age (mean = 23.37 years, standard deviation = 2.35). Our findings highlighted the existence of associations between APC, identity, and internalizing difficulties. Specifically, APC…
Facing the music : a critical enquiry into 'the dodo-bird verdict' to develop music psychotherapy theory
2015
‘The dodo-bird verdict’ represents a boggling outcome of research that shows no significant difference between the outcomes of a variety of psychotherapy treatments. Not being able to scientifically discriminate between psychotherapeutic treatments, casts doubt on their theoretical underpinnings, and even on their efficacy. This in turn presents professionals who use psychotherapeutic techniques - including music therapists - with a conundrum: What can explain this inability? And what can be done to solve the problem? Conceptual research methods were used to analyse literature in order to answer these questions. Various weaknesses were identified, both in theory construction and in research…
Unlawful Aid and Public Undertakings: Vertical Direct Effect of Article 108(3), third sentence TFEU
2021
This paper addresses the position of public undertakings that may appear in a State aid law-related context in their capacity of intermediaries or grantors of aid vis-à-vis Article 108(3), third sentence, TFEU, to check whether the standstill obligation directly applies to public undertakings where they act to grant or disburse State aid. Public undertakings must refrain from granting aid in breach of the standstill obligation, as addressees of the standstill obligation. Where a public undertaking fails to apply Article 108(3) TFEU, it opens itself to claims based on Union law, including claims for damages. Union law is stated as it stood on 20 June 2021.
Ultrafast Interface Charge Separation in Carbon Nanodot-Nanotube Hybrids
2021
Carbon dots are an emerging family of zero-dimensional nanocarbons behaving as tunable light harvesters and photoactivated charge donors. Coupling them to carbon nanotubes, which are well-known electron acceptors with excellent charge transport capabilities, is very promising for several applications. Here, we first devised a route to achieve the stable electrostatic binding of carbon dots to multi- or single-walled carbon nanotubes, as confirmed by several experimental observations. The photoluminescence of carbon dots is strongly quenched when they contact either semiconductive or conductive nanotubes, indicating a strong electronic coupling to both. Theoretical simulations predict a favo…
Analysis of the determinants of entrepreneurial intention: the case of Burkina Faso
2018
International audience; In this study, we propose to analyze students' entrepreneurial intention, drawing on Lazear's (2004) self-selection model. This model captures the role of "human capital" in employment assignment and emphasizes the importance of the variety of skills in the individual's entrepreneurial orientation. For this purpose, we have a database collected in 2017 from over 1000 students at Ouaga I and Ouaga II universities in Burkina Faso. The results of estimates obtained using the quantile regression method show a positive and significant effect of the diversity of skills on the intention score, mainly at the median level. Even if the effect is not strong, this result support…
Rayleigh-instability-driven dewetting of thin Au and Ag films on indium-tin-oxide surface under nanosecond laser irradiations
2013
Investigations have been carried out on laser-beam-induced nanoparticle (NP) formation in thin (5 nm) Au and Ag films on indium-tin-oxide substrate. After the irradiation the films were observed to break-up into NPs through a dewetting mechanism. This mechanism was investigated as a Rayleigh-instability- driven process. In fact, for each used laser fluence, the resulting Au and Ag NPs' mean size and surface-to-surface mean distance were quantified and correlated between them in the framework of the Rayleigh-instability theory showing an excellent agreement. © The Institution of Engineering and Technology 2013.
Thermal bleaching of gamma-induced-defects in optical fibers
2012
International audience; Ge-doped and F-doped gamma-irradiated fibers with a maximum accumulated dose of 10 MGy were subjected to isochronal annealing treatments up to 750°C. The thermal treatment influence on the point defect generation and transformation were investigated through Radiation Induced Attenuation (RIA) changes in the visible and IR spectral domains. The thermal bleaching of gammainduced-defects depends on both temperature and composition of optical fibers.
