“…The maximum resistivity occurs at around ∼60 K, followed by an abrupt drop (Figure h). Compared with the transport properties of the endmembers at room temperature, the electrical resistivity of (NbTaTi) 0.33 S 3 (∼1.7 Ω·cm) is close to that of TiS 3 with ρ (300 K) ∼ 2 Ω·cm. , The room-temperature resistivity of TaS 3 is at least 3 orders of magnitude smaller, and that of NbS 3 varies by the polymorphs. , The anomaly observed in the resistivity of (NbTaTi) 0.33 S 3 is attributed to distinct phase transitions associated with the CDW state. The phase transition temperatures are determined as the local maximum in the temperature-dependent logarithmic derivative of the resistance plot, , which are around 44 and 102 K, respectively (inset of Figure h).…”

“…One-dimensional (1D) van der Waals (vdW) materials, such as nanofibers, nanoribbons, and nanotubes, have strong covalent bonds along the atomic chains and vdW bonds in the direction perpendicular to the chains. − The reduced in-plane structural symmetry of 1D materials leads to strong anisotropies in their electrical, optical, and magnetic properties, − thus, broadening their applications in electronic devices. − Among the 1D materials, there is a rapid emergence of interests in the transition metal trichalcogenides (TMTC) family because of its chemical and structural tunability, which comes from a diverse choices of cationic and anionic sites, as well as the rich structural polymorphs. ,− …”

One-dimensional (1D) materials demonstrate anisotropic in-plane physical properties that enable a wide range of functionalities in electronics, photonics, valleytronics, optoelectronics, and catalysis. Here, we undertake an in-depth study of the growth mechanism for equimolar midentropy alloy of (NbTaTi)0.33S3 nanoribbons as a model system for 1D transition metal trichalcogenide structures. To understand the thermodynamic and kinetic effects in the growth process, the energetically preferred phases at different synthesis temperatures and times are investigated, and the phase evolution is inspected at a sequence of growth steps. It is uncovered that the dynamics of the growth process occurs at four different stages via preferential incorporation of chemical species at high-surface-energy facets. Also, a sequence of temperature and time dependent nonuniform to uniform phase evolutions has emerged in the composition and structure of (NbTaTi)0.33S3 which is described based on an anisotropic vapor–solid (V–S) mechanism. Furthermore, direct evidence for the 3D structure of the charge density wave (CDW) phase (width less than 100 nm) is provided by three-dimensional electron diffraction (3DED) in individual nanoribbons at cryogenic temperature, and detailed comparisons are made between the phases obtained before and after CDW transformation. This study provides important fundamental information for the design and synthesis of future 1D alloy structures.

The unique electronic and catalytic properties emerging from low symmetry anisotropic (1D and 2D) metal chalcogenides (MCs) have generated tremendous interest for use in next generation electronics, optoelectronics, electrochemical energy storage devices, and chemical sensing devices. Despite many proof-of-concept demonstrations so far, the full potential of anisotropic chalcogenides has yet to be investigated. This article provides a comprehensive overview of the recent progress made in the synthesis, mechanistic understanding, property modulation strategies, and applications of the anisotropic chalcogenides. It begins with an introduction to the basic crystal structures, and then the unique physical and chemical properties of 1D and 2D MCs. Controlled synthetic routes for anisotropic MC crystals are summarized with example advances in the solution-phase synthesis, vapor-phase synthesis, and exfoliation. Several important approaches to modulate dimensions, phases, compositions, defects, and heterostructures of anisotropic MCs are discussed. Recent significant advances in applications are highlighted for electronics, optoelectronic devices, catalysts, batteries, supercapacitors, sensing platforms, and thermoelectric devices. The article ends with prospects for future opportunities and challenges to be addressed in the academic research and practical engineering of anisotropic MCs.

“…Structural anisotropy at the atomic level shows up on the macroscopic level through preferential growth along the b -axis (Figure B), resulting in distinctive needle-like microstructures known as whiskers or (nano)ribbons, as well as related anisotropic physical properties, which can be observed at room temperature and ambient pressure (see e.g., refs − ).

Transition metal trichalcogenides (TMTCs) offer remarkable opportunities for tuning electronic states through modifications in chemical composition, temperature, and pressure. Despite considerable interest in TMTCs, there remain significant knowledge gaps concerning the evolution of their electronic properties under compression. In this study, we employ experimental and theoretical approaches to comprehensively explore the high-pressure behavior of the electronic properties of TiS 3 , a quasi-one-dimensional (Q1D) semiconductor, across various temperature ranges. Through high-pressure electrical resistance and magnetic measurements at elevated pressures, we uncover a distinctive sequence of phase transitions within TiS 3 , encompassing a transformation from an insulating state at ambient pressure to the emergence of an incipient superconducting state above 70 GPa. Our findings provide compelling evidence that superconductivity at low temperatures of ∼2.9 K is a fundamental characteristic of TiS 3 , shedding new light on the intriguing highpressure electronic properties of TiS 3 and underscoring the broader implications of our discoveries for TMTCs in general.
