Controlling interfacial interactions in magnetic/topological insulator heterostructures is a major challenge for the emergence of novel spin-dependent electronic phenomena. As for any rational design of heterostructures that rely on proximity effects, one should ideally retain the overall properties of each component while tuning interactions at the interface. [...]

24 p, 2.9 MB Theoretical studies of Rashba and Dresselhaus effects in hybrid organic-inorganic perovskites for optoelectronic applications / Pedesseau, Laurent (Université Européenne de Bretagne) ; Kepenekian, Mikaël (Institut des Sciences Chimiques de Rennes) ; Robles, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Sapori, Daniel (Université Européenne de Bretagne) ; Katan, Claudine (Institut des Sciences Chimiques de Rennes) ; Even, Jacky (Université Européenne de Bretagne)
In this paper, we propose a description of the Rashba-Dresselhaus effect in Hybrid Organic Perovskite (HOP). We show how the loss of the inversion symmetry leads to the loss of the spin degeneracy. An example of structure where both Rashba and Dresselhaus operate is illustrated with the formamidinium tin iodide CH(NH)SnI. [...]

Bulk and single-layer 2H-NbSe₂ exhibit identical charge density wave order (CDW) with a quasi-commensurate 3 × 3 superlattice periodicity. Here we combine scanning tunnelling microscopy (STM) imaging at T = 1 K of 2H-NbSe₂ with first-principles density functional theory (DFT) calculations to investigate the structural atomic rearrangement of this CDW phase.

8 p, 3.1 MB 2 × 2 charge density wave in single-layer TiTe₂ / Guster, Bogdan (Institut Català de Nanociència i Nanotecnologia) ; Robles, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Pruneda, Miguel (Institut Català de Nanociència i Nanotecnologia) ; Canadell Casanova, Enric (Institut de Ciència de Materials de Barcelona) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia)
A density functional theory study concerning the origin of the recently reported 2 × 2 charge density wave (CDW) instability in single-layer TiTe₂ is reported. It is shown that, whereas calculations employing the semi-local functional PBE favor the undistorted structure, the hybrid functional HSE06 correctly predicts a 2 × 2 distortion. [...]

The interaction among magnetic moments screened by conduction electrons drives quantum phase transitions between magnetically ordered and heavy-fermion ground states. Here, starting from isolated magnetic impurities in the Kondo regime, we investigate the formation of the finite size analogue of a heavy Fermi liquid. [...]

Metallocene (MCp) wires have recently attracted considerable interest in relation to molecular spintronics due to predictions concerning their half-metallic nature. This exciting prospect is however hampered by the little and often-contradictory knowledge we have concerning the metallocene self-assembly and interaction with a metal. [...]

Metallorganic molecules have been proposed as excellent spin filters in molecular spintronics because of the large spin polarization of their electronic structure. However, most of the studies involving spin transport have disregarded fundamental aspects such as the magnetic anisotropy of the molecule and the excitation of spin-flip processes during electron transport.
