Essas questões são problematizadas a partir de seu enquadramento social e histórico, no qual desenvolveu o conjunto das vivências da família. Por meio de seu microcosmo, foi observado o esforço e a tentativa de (re)construir, em seu exílio, uma cultura alemã e europeia juntamente com a brasileira. Portanto, esta pesquisa apoia-se na análise da materialidade da Biblioteca, entendendo-a como expressão do contexto social em que ela foi formada. Dessa forma, a enquadramos como produto e produtora de cultura, e como lugar de memória. A partir dos livros presentes em sua composição, problematizamos o relacionamento entre suas leituras e seu contexto social. Além disso, por meio da investigação da Biblioteca Cidadã e de algumas produções textuais serão questionados os posicionamentos de Michael Traumann como guardião de uma cultura que temia a decadência e de uma memória familiar voltada ao elitismo cultural. / This research tries to analyze the identity and memorie constructions of Michael Traumann and his family, through the Traumann’s Library, and to observe the cultural practice and world visions that it shows. These questions will be problematized from his social and historical place, in which he has developed his family context. Through his microcosm, we will be observe his effort and his try to (re)build, in his volunteer exile, a German, European and Brazilian culture. Therefore, we will consider as acculturated/acculturatingand as a memory place. Next, will be questioned Michael Traumann’s positions as a keeper of a culture that was afraid of a decadency and of a family memory turned to the culture elitism.

For this reason, this study aimed to examine their previous experiences the War with the objective of characterizing their worldview forged in accord with their identity; and consider its performance writing after the confrontation in an attempt to grasp the depth of the modification effected by experience during his stay in Spain, understanding it within a context of dispute of memories. / Este trabalho tem por objeto analisar a experi?ncia da Guerra Civil Espanhola (1936-1937) atrav?s dos escritos do ingl?s George Orwell, buscando perceber, em sua compreens?o sobre o evento, o olhar que sua condi??o de estrangeiro imprimiu ao conflito e as modifica??es que a realidade do front efetuaram na vis?o que possu?a sobre seu pr?prio pa?s, a Inglaterra.

La thèse de Giovanni BETTI BENEVENTI portes sur la caractérisation électrique et la modélisationphysique de dispositifs de mémoire non-volatile à changement de phase. Cette thèse a été effectuée dans le cadre d’une cotutelle avec l’Università degli Studi di Modena e Reggio Emilia (Italie).Le manuscrit en anglais comporte quatre chapitres précédés d’une introduction et terminés par uneconclusion générale.Le premier chapitre présent un résumé concernant l’état de l’art des mémoires a changement de phase. Le deuxième chapitre est consacré aux résultats de caractérisation matériau et électrique obtenus sur déposition blanket et dispositifs de mémoire à changement de phase (PCM) basées sur le nouveau matériau GeTe dopé carbone (GeTeC).Le chapitre trois s’intéresse à l’implémentation et à la caractérisation expérimentale d’un setup demesure de bruit a basse fréquence sur dispositifs électroniques a deux terminaux développé auxlaboratoires de l’Università degli Studi di Modena e Reggio Emilia en Italie.Enfin, dans le dernier chapitre est présentée une analyse rigoureuse de l’effet d’auto-chauffage Joulesur la caractéristique I-V des mémoires a changement de phase intégrant le matériau dans la phase polycristalline. / Within this Ph.D. thesis work new topics in the field of Non-Volatile Memories technologies have been investigated, with special emphasis on the study of novel materials to be integrated in Phase-Change Memory (PCM) devices, namely:(a) Investigation of new phase-change materialsWe have fabricated PCM devices integrating a novel chalcogenide material: Carbon-doped GeTe (or simply, GeTeC). We have shown that C doping leads to very good data retention performances: PCM cells integrating GeTeC10% can guarantee a 10 years fail temperature of about 127°C, compared to the 85°C of GST. Furthermore, C doping reduces also fail time dispersion. Then our analysis has pointed out the reduction of both RESET current and power for increasing carbon content. In particular, GeTeC10% PCM devices yield about a 30% of RESET current reduction in comparison to GST and GeTe ones, corresponding to about 50% of RESET energy decrease.Then, resistance window and programming time of GeTeC devices are comparable to those of GST.(b) Advanced electrical characterization techniquesWe have implemented, characterized and modeled a measurement setup for low-frequency noise characterization on two-terminal semiconductor devices.(c) Modeling for comprehension of physical phenomenaWe have studied the impact of Self-induced Joule-Heating (SJH) effect on the I-V characteristics of fcc polycrystalline-GST-based PCM cells in the memory readout region. The investigation has been carried out by means of electrical characterization and electro-thermal simulations.
