Bulk intergrowth of a topological insulator with a room-temperature ...
2012年4月19日 · We demonstrate that the layered room-temperature ferromagnet Fe${}_{7}$Se${}_{8}$ and the topological insulator Bi${}_{2}$Se${}_{3}$ form crystallographically oriented bulk composite intergrowth crystals. The morphology of the intergrowth in real space and reciprocal space is described.
topological insulator Bi2Se3 form crystallographically oriented bulk composite intergrowth crystals. The morphology of the intergrowth in real space and reciprocal space is described. The basal planes of Bi2Se3 and Fe7Se8 are parallel in the micron-scale intergrowth, and hence the good cleavage inherent to the bulk phases is retained.
Long-wavelength excitations in incommensurate intergrowth compounds ...
Abstract. There exists a variety of compounds consisting of two (or more) interpenetrating incommensurate lattices, e.g., , tetrathiafulvalene iodide (TTF- ), Nowotny phases. In such materials one expects new hydrodynamic modes associated with …
Phase intergrowth in …
1993年11月1日 · The intergrowth phenomenon allows one to change the structure continuously from one pure phase to another one, a fact that is experimentally observed when the oxygen pressure during deposition is changed.
Phys. Rev. B 81, 245119 (2010) - Electronic structure and ...
2010年6月17日 · The layered PbTe: Bi 2 Te 3 intergrowth compound, PbBi 2 Te 4, and related materials are investigated using first-principles calculations and Boltzmann transport theory.
Caption Fig. A1. Structural measurements showing that the Cu-doped Bi2Se3 remain single phase. Cu-intergrowth would appear as extra peaks in the diffraction plots (a-c) or as clusters in the topographical images (d-e). (a) X-ray diffraction …
Design and synthesis of three-dimensional hybrid Ruddlesden …
2024年5月8日 · In R-P phases, intergrowth is well known in the short range; however, no existing compounds have been reported to have different mixed in bulk single crystals. Here we design a hybrid R-P nickelate by alternatively stacking bilayers, which is the active structural motif in the superconductor and single layers of the antiferromagnetic insulator .
2022年9月28日 · a recent study unveils the intergrowth of octahedral (O-type) and prismatic (P-type) Na layers during the phase transformation for many layered Na TM oxides at highly charged states. [19] The intergrowth of different layers forms hybrid-phased compounds. The first reported hybrid-phased TM oxide is Na 0.667 (Fe 0.5 Mn 0.5)O 2.
Phys. Rev. B 70, 165401 (2004) - ${M}_{n+1}A{X}_{n}$ phases in the ...
2004年10月1日 · The latter two structures can be viewed as an intergrowth of 2 and 3 or 3 and 4 M layers between each A layer. In addition, epitaxial films of Ti 5 Si 3 C x were deposited and Ti 5 Si 4 is also observed.
Magnetic order in the double-layer manganites
2008年8月21日 · From M 55 n NMR spectroscopy, such a response is unambiguously assigned to the intergrowth of a ferromagnetic pseudocubic phase (La 1 − z Pr z) 1 − x Sr x MnO 3, with an overall volume fraction estimated as 0.5%–0.7% from magnetometry.
