10 p, 3.3 MB Changes of structure and bonding with thickness in chalcogenide thin films / Ronneberger, Ider (Jülich Aachen Research Alliance) ; Zanolli, Zeila (Institut Català de Nanociència i Nanotecnologia) ; Wuttig, Matthias (Jülich Aachen Research Alliance) ; Mazzarello, Riccardo (Jülich Aachen Research Alliance)
Extreme miniaturization is known to be detrimental for certain properties, such as ferroelectricity in perovskite oxide films below a critical thickness. Remarkably, few-layer crystalline films of monochalcogenides display robust in-plane ferroelectricity with potential applications in nanoelectronics. [...]

12 p, 1004.2 KB Spectroscopic properties of few-layer tin chalcogenides / Dewandre, Antoine (Université de Liège. Department of Physics) ; Verstraete, Matthieu J. (Université de Liège. Department of Physics) ; Grobert, Nicole (University of Oxford. Department of Materials) ; Zanolli, Zeila (Institut Català de Nanociència i Nanotecnologia)
Stable structures of layered SnS and SnSe and their associated electronic and vibrational spectra are predicted using first-principles DFT calculations. The calculations show that both materials undergo a phase transformation upon thinning whereby the in-plane lattice parameters ratio a/b converges towards 1, similar to the high-temperature behaviour observed for their bulk counterparts. [...]

We employ an ab-initio structure search algorithm to explore the configurational space of bismuth in quasi-two dimensions. A confinement potential is introduced to restrict the movement of atoms within a predefined thickness to find the stable and metastable forms of monolayer Bi. [...]

14 p, 5.9 MB Hybrid quantum anomalous Hall effect at graphene-oxide interfaces / Zanolli, Zeila (Institut Català de Nanociència i Nanotecnologia) ; Niu, C. (Peter Grünberg Institut) ; Bihlmayer, G. (Peter Grünberg Institut) ; Mokrousov, Y. (Johannes Gutenberg University Mainz) ; Mavropoulos, P. (Peter Grünberg Institut) ; Verstraete, Matthieu J. (Université de Liège) ; Blügel, S. (Peter Grünberg Institut)
Interfaces are ubiquitous in materials science, and in devices in particular. As device dimensions are constantly shrinking, understanding the physical properties emerging at interfaces is crucial to exploit them for applications, here for spintronics. [...]

10 p, 2.0 MB Spin states protected from intrinsic electron-phonon coupling reaching 100 ns lifetime at room temperature in MoSe₂ / Ersfeld, Manfred (RWTH Aachen University) ; Volmer, Frank (RWTH Aachen University) ; Melo, Pedro Miguel M.C. de (Université de Liège. Complex and Entangled Systems from Atoms to Materials) ; Winter, Robin de (RWTH Aachen University) ; Heithoff, Maximilian (RWTH Aachen University) ; Zanolli, Zeila (Institut Català de Nanociència i Nanotecnologia) ; Stampfer, Cristoph (RWTH Aachen University) ; Verstraete, Matthieu J. (Université de Liège. Complex and Entangled Systems from Atoms to Materials) ; Beschoten, Bernd (RWTH Aachen University)
We present time-resolved Kerr rotation measurements, showing spin lifetimes of over 100 ns at room temperature in monolayer MoSe. These long lifetimes are accompanied by an intriguing temperature-dependence of the Kerr amplitude, which increases with temperature up to 50 K and then abruptly switches sign. [...]
