The design and formation of van der Waals (vdW) heterostructures with different two-dimensional (2D) materials provide an opportunity to create materials with extraordinary physical properties tailored toward specific applications. Mechanical exfoliation of natural vdW materials has been recognized as an effective way for producing high-quality ultrathin vdW heterostructures. Abramovite is one of such naturally occurring vdW materials, where the superlattice is composed of alternating Pb2BiS3 and SnInS4 2D material lattices. The forced commensuration between the two incommensurate constituent 2D material lattices induces in-plane structural anisotropy in the formed vdW heterostructure of abramovite, even though the individual 2D material lattices are isotropic in nature. Here, we show that ultrathin layers of vdW heterostructures of abramovite can be achieved by mechanical exfoliation of the natural mineral. Furthermore, the structural anisotropy induced highly anisotropic vibrational and optical responses of abramovite thin flakes are demonstrated by angle-resolved polarized Raman scattering, linear dichroism, and polarization-dependent third-harmonic generation. Our results not only establish abramovite as a promising natural vdW material with tailored linear and nonlinear optical properties for building future anisotropic integrated photonic devices, but also provide a deeper understanding of the origin of structural, vibrational and optical anisotropy in vdW heterostructures.

“…The structure is composed of stacked, weakly coupled [Pb 2 BiS 3 ] layers and [AuTe 2 ] sheets. Magneto-transport measurements showed that [Pb 2 BiS 3 ][AuTe 2 ] is a multiband semimetal with strong spin–orbit coupling. , Actually, in nature, there are several other interesting 2D materials, such as the so-called cylindrite (FeSn 4 Pb 3 Sb 2 S 14 ), abramovite (Pb 2 SnInBiS 7 ), merelaniite (Mo 4 Pb 4 VSbS 15 ), levyclaudite (Pb 8 Sn 7 Cu 3 (Bi,Sb) 3 S 28 ), and jaszczakite ([(Pb,Bi) 3 S 3 ][AuS 2 ]), to name a few. Recently, it was demonstrated that the mineral franckeite can be exfoliated into a few layers toward efficient photodetectors .…”

We report the two-dimensional (2D) natural heterostructure [Pb3.1Sb0.9S4][AuxTe2-x] (x = 0.52 − 0.36) which shows anomalous, transverse nonsaturating negative magnetoresistance (MR). For x = 0.52, the material has a commensurately modulated structure with alternating [Pb3.1Sb0.9S4] rocksalt layers and atomically thin [AuxTe2-x] sheets, as determined by single crystal X-ray diffraction using a (3 + 1)-dimensional space group; for other x compositions, the modulated structures are absent and the Au and Te atoms are disordered. The transport properties in this system in low temperature (< 100 K) are dominated by an unusual 2D hopping mechanism, while at room temperature a high carrier mobility of ~1352 cm 2 V-1 s-1 is obtained (x = 0.36). The confined electrons within the [AuxTe2-x] layers are also exposed to inter-layer coupling with the insulating [Pb3.1Sb0.9S4] layers and as a result the properties of the heterostructures emerge not only from the constituent layers, but also the interactions between them. Furthermore, the various Au and Te coordination patterns found in the [AuxTe2-x] sheets as a function of x further contribute to a unique electronic structure that leads to the anomalous non-saturating negative MR with different field dependent behaviors. First-principles calculations indicate that the [AuxTe2-x] sheets are responsible for the unusual electrical transport properties in this 2D system.

Abstract:Merelaniite is a new mineral from the tanzanite gem mines near Merelani, Lelatema Mountains, Simanjiro District, Manyara Region, Tanzania. It occurs sporadically as metallic dark gray cylindrical whiskers that are typically tens of micrometers in diameter and up to a millimeter long, although a few whiskers up to 12 mm long have been observed. The most commonly associated minerals include zoisite (variety tanzanite), prehnite, stilbite, chabazite, tremolite, diopside, quartz, calcite, graphite, alabandite, and wurtzite. In reflected polarized light, polished sections of merelaniite are gray to white in color, show strong bireflectance and strong anisotropism with pale blue and orange-brown rotation tints. Electron microprobe analysis (n = 13), based on 15 anions per formula unit, gives the formula An arsenic-rich variety has also been documented. X-ray diffraction, electron diffraction, and high-resolution transmission electron microscopy show that merelaniite is a member of the cylindrite group, with alternating centered pseudo-tetragonal (Q) and pseudo-hexagonal (H) layers with respective PbS and MoS 2 structure types. The Q and H layers are both triclinic with space group C1 or C1. The unit cell parameters for the Q layer are: a = 5.929 (8) and is named after the locality of its discovery in honor of the local miners.
