Enhanced ferromagnetism in artificially stretched lattice in quasi two-dimensional Cr2Ge2Te6
Hiroshi Idzuchi, Andres E Llacsahuanga Allcca, Anh Khoa Augustin Lu +9
In the fundamental understanding of magnetic interactions between atoms in solids, the crystal lattice is one of the key parameters. As the effective tool for controlling the latti…
Hole-doping induced ferromagnetism in 2D materials
R. Meng, L. M. C. Pereira, J. P. Locquet +3
Two-dimensional (2D) ferromagnetic materials are considered as promising candidates for the future generations of spintronic devices. Yet, 2D materials with intrinsic ferromagnetis…
On the origin of supertetragonality in BaTiO
Simon Mellaerts, Jin Won Seo, Valeri Afanas'ev +2
Understanding ferroelectricity is of both fundamental and technological importance to further stimulate the development of new materials designs and manipulations. Here, we perform…
Advanced DFT-NEGF transport techniques for novel 2D-material and device exploration including HfS2/WSe2 van-der-Waals Heterojunction TFET and WTe2/WS2 metal/semiconductor contact
Aryan Afzalian, Elaheh Akhoundi, Gautam Gaddemane +2
We present, here, advanced DFT-NEGF techniques that we have implemented in our ATOmistic MOdelling Solver, ATOMOS, to explore transport in novel materials and devices and in partic…
An efficient direct band-gap transition in germanium by three-dimensional strain
Simon Mellaerts, Valeri Afanasiev, Jin Won Seo +2
Complementary to the development of highly three-dimensional (3D) integrated circuits in the continuation of Moore's law, there has been a growing interest in new 3D deformation st…
Quarter-filled Kane-Mele Hubbard model: Dirac half-metals
Simon Mellaerts, Ruishen Meng, Valeri Afanasiev +3
Recent experimental success in the realization of two-dimensional (2D) magnetism has stimulated the search for new magnetic 2D materials with strong magnetic anisotropy and high Cu…
Two-dimensional honeycomb-kagome V2O3: a robust room-temperature magnetic Chern insulator interfaced with graphene
Simon Mellaerts, Ruishen Meng, Mariela Menghini +4
The possibility of dissipationless chiral edge states without the need of an external magnetic field in the quantum anomalous Hall effect (QAHE) offers a great potential in electro…
Towards twin-free molecular beam epitaxy of 2D chalcogenides explained by stronger interlayer van der Waals coupling
Wouter Mortelmans, Karel De Smet, Ruishen Meng +4
Defect-free epitaxial growth of 2D materials is one of the holy grails for a successful integration of van der Waals (vdW) materials in the semiconductor industry. The large-area (…
Collapse of the low temperature insulating state in Cr-doped VO thin films
Pía Homm, Leander Dillemans, Mariela Menghini +10
We have grown epitaxial Cr-doped VO thin films with Cr concentrations between and on -AlO by oxygen-assisted molecular beam epitaxy. For the high…
Getting through the nature of silicene: sp2-sp3 two-dimensional silicon nanosheet
E. Cinquanta, E. Scalise, D. Chiappe +5
By combining experimental techniques with ab-initio density functional theory calculations, we describe the Si/Ag(111) two-dimensional system in terms of a sp2-sp3 crystalline form…
Noninvasive Embedding of Single Co Atoms in Ge(111)2x1 Surfaces
D. A. Muzychenko, K. Schouteden, M. Houssa +2
We report on a combined scanning tunneling microscopy (STM) and density functional theory (DFT) based investigation of Co atoms on Ge(111)2x1 surfaces. When deposited on cold surfa…
Aging process of electrical contacts in granular matter
S. Dorbolo, M. Ausloos, N. Vandewalle +1
The electrical resistance decay of a metallic granular packing has been measured as a function of time. This measurement gives information about the size of the conducting cluster…
