SUMMARY:Soutenance de Thèse par Corentin GUERIN (CEA-Irig/Pheliqs)
DESCRIPTION:Réalisation d’hétérostructures III-Nitrures pour l’émission UV profond : du matériau au dispositif\nRésumé : \nNous explorons ici plusieurs sujets connexes autour de l’émission dans la gamme UV-C pour des applications dans le domaine de la désinfection. Dans un premier temps\, nous étudions la croissance de l’AlN en structure nanofil par reprise d’épitaxie réalisée par une technique d’épitaxie par jets moléculaires (EJM) sur des nano-piliers de GaN. Nous étudions les conditions optimales de croissance EJM puis établissons un mode de croissance optimisé pour nos nanofils d’AlN utilisant une méthode de croissance alternée (Migration Enhanced Epitaxy). Suite à l’observation de défauts d’empilements étendus dans le plan basal des sections d’AlN\, assimilables à des inclusions cubiques le long de la matrice wurtzite\, nous identifions le caractère luminescent de ces défauts à basse température et établissons un modèle prédictif liant le nombre de plans de la faute d’empilement à son énergie d’émission. Dans un troisième temps\, nous étudions les propriétés de luminescence en température et résolues en temps d’un puits quantique GaN/AlN ultra-fin\, d’épaisseur graduée inférieure à une monocouche\, qui émet dans l’UV-C profond entre 240 nm et 220 nm. Etablissant les propriétés de la structure en luminescence résolue en temps\, nous établissons un modèle basé sur la fuite thermoionique de l’électron dans la barrière AlN\, permettant d’expliquer la chute de rendement quantique externe observée dans les émetteurs UV-C profonds. En outre\, nous détaillons la réalisation d’une Diode Électroluminescente réalisée par EJM et la réalisation du contact p. Nous démontrons une émission à 260 nm en électroluminescence\, pour un très faible EQE de 5.10−3%. Enfin\, nous proposons une méthode de mesure du rendement radiatif par excitation électronique\, basée sur l’utilisation d’une sphère intégrante à l’intérieur d’un microscope électronique.​ \n

SUMMARY:Chung-Hou CHUNG (1 Department of Electrophysics\, National Yang Ming Chiao Tung University\, Hsinchu\, Taiwan -  2 Physics Division\, National center for Theoretical Sciences\, Taipei\,Taiwan)
DESCRIPTION:A theory for quantum-critical Planckian strange metal phase in high-Tc cuprate superconductors\nRésumé : \nThe strange metallic state showing incoherent charge transport with universal linear-in-temperature scattering rate: 1/τ = αP kB T / ħ with αP ~ 1 and logarithmic-in-temperature singular specific heat coefficient\, so-called “Planckian metal”\, has been observed in various high-Tc cuprate superconductors over a finite range in doping near optimal doping [1]. Understanding this state is believed to be the key to revealing the mechanism for high-Tc superconductivity. Here\, we propose a generic microscopic mechanism for this state based on quantum-critical local bosonic charge Kondo fluctuations coupled to both spinon and a heavy conduction-electron Fermi surfaces within the heavy-fermion formulated slave-boson t-J model [2]. Our theory is motivated by the striking similarity in strange metal phenomenology between cuprates and heavy-fermion Kondo lattice systems [3]. By a controlled perturbative renormalization group analysis of our effective heavy-fermion model\, we examine the competition between the pseudogap phase\, characterized by Anderson’s Resonating-Valence-Bond spin-liquid made of fermionic spin-singlet spinons\, and the Fermi-liquid state modeled by coherent electron hopping (charge Kondo hybridization). We find an extended quantum-critical metallic phase with a universal Planckian ħω/kBT scaling in scattering rate near a localized-delocalized (pseudogap-to-Fermi liquid) charge-Kondo breakdown transition of the model. The d-wave superconducting ground state emerges near the transition. Unprecedented qualitative and quantitative agreements are reached between our theoretical predictions and various experiments\, including ħω/kBT scaling in optical conductivity [4]\, universal doping-insensitive field-to-temperature (B/T-) scaling in magnetoresistance [5]\, singular specific heat coefficient [6]\, marginal Fermi-liquid spectral function observed in ARPES [7]\, and Fermi surface reconstruction observed in Hall coefficients in various overdoped cuprates [5\,8]. We further applied this framework to obtain a universal quantum-critical B/T-scaling in magneto-transport and unify the B-linear and T-linear Planckian scattering rate observed in LSCO over an extended doping range\, pointing toward a unified quantum–critical origin of Planckian transport in cuprates [9]. This universal Planckian metal phase can be realized within a solvable large-N multi-channel Kondo lattice model generalized from this heavy-fermion formulated tJ model [10]. Our mechanism offers a microscopic understanding of the quantum-critical Planckian metal phase observed in cuprates and its link to the pseudogap\, d-wave superconducting\, and Fermi liquid phases. It offers a promising route for understanding how d-wave superconductivity emerges from such a strange metal phase in cuprates–one of the long-standing open problems in condensed matter physics since 1990s. \nReferences  \n\nLegros et al.\, Nat.
