We use confocal Raman microscopy and a recently proposed vector analysis scheme to investigate the nanoscale origin of strain and carrier concentration in exfoliated graphene-hexagonal boron nitride (hBN) heterostructures on silicon dioxide (SiO). [...]

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) ; Ordejón Rontomé, 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. [...]
