Noble‐metal chalcogenides, dichalcogenides, and phosphochalcogenides are an emerging class of two‐dimensional materials. Quantum confinement (number of layers) and defect engineering enables their properties to be tuned over a broad range, including metal‐to‐semiconductor transitions, magnetic ordering, and topological surface states. They possess various polytypes, often of similar formation energy, which can be accessed by selective synthesis approaches. They excel in mechanical, optical, and chemical sensing applications, and feature long‐term air and moisture stability. In this Minireview, we summarize the recent progress in the field of noble‐metal chalcogenides and phosphochalcogenides and highlight the structural complexity and its impact on applications.

Emerging two‐dimensional (2D) materials have stimulated tremendous scientific and industrial interests due to their diverse and tunable physical, chemical, and mechanical properties. The scalable production of high‐quality wafer‐scale 2D materials has become significantly essential to bring us closer to practical industrial applications, particularly in electronic devices. Vapor‐phase growth provides attractive opportunities for the synthesis of large‐area and high‐quality 2D materials. In this review, we will emphasize vapor‐phase growth strategies from three aspects, including suppressing nucleation, seamless stitching, and evolutionary selection growth. We discuss the general understanding of the related fundamental mechanism and specific parameter optimization from precursors and substrate design to the adjusting of growth parameters (temperature and pressure). Meanwhile, we present other strategies to produce various kinds of wafer‐scale 2D materials. Finally, we conclude the current challenges and future directions in this developing field. This work may inspire researchers to better design routes in the synthesis of wafer‐scale 2D materials with high quality.

Emerging classes of 2D noble-transition-metal dichalcogenides (NTMDs) stand out for their unique structure and novel physical properties in recent years. With the nearly full occupation of the d orbitals, 2D NTMDs are expected to be more attractive due to the unique interlayer vibrational behaviors and largely tunable electronic structures compared to most transition metal dichalcogenide semiconductors. The novel properties of 2D NTMDs have stimulated various applications in electronics, optoelectronics, catalysis, and sensors. Here, the latest development of 2D NTMDs are reviewed from the perspective of structure characterization, preparation, and application. Based on the recent research, the conclusions and outlook for these rising 2D NTMDs are presented.Very recently, group-10 noble TMDs (NTMDs) have been reintroduced as new 2D materials, displaying many fascinating properties including widely tunable bandgap, moderate carrier mobility, anisotropy, and ultrahigh air stability. [34][35][36][37] Unlike most common TMDs with less d-electrons, the d orbitals of NTMDs are nearly fully occupied, and the corresponding p z orbital of interlayer chalcogen atoms are highly hybridized, leading to strong layer-dependent properties and interlayer interactions. [36,38] For example, it has been predicted that PtS 2 holds a layerdependent bandgap from 0.25 to 1.6 eV, [36] bridging the gap between graphene and most TMDs that with large gap. Besides, the calculated mobility based on PtS 2 , PtSe 2 , and PdSe 2 field effect transistors (FETs) is as high as ≈200 cm 2 V −1 s −1 , [36,37,39] larger than most other TMDs. Moreover, NTMDs possess high air stability, and the performance of the PtSe 2 FET remains nearly unchanged after 5 months air exposure. [37] Specially, PdS 2 and PdSe 2 hold novel puckered pentagonal structure and thus exhibit very interesting anisotropic properties, [39,40] which may bring even more physics and applications. Additionally, PtTe 2 and PdTe 2 are type-II Dirac fermions, making them great platform for investigating novel transport related to topological phase transition and chiral anomaly. [41,42] Nowadays, the 2D NTMDs is becoming increasingly fascinating in the 2D materials research.In this review, we highlight a comprehensive report of the recent research progress in 2D NTMDs such as PtS 2 , PtSe 2 , PdS 2 , PdSe 2 , PtTe 2 , and PdTe 2 . In order to understand the internal relation between structural characteristics and physical properties, this review begins with a brief summary of the structure of 2D NTMDs and their transitions. Then, some recent progress on their preparation methods, including mechanical exfoliation of the bulk materials, chemical vapor deposition (CVD), molecular beam epitaxy (MBE), is reviewed along with the performance of the resulting 2D NTMDs as high-performance candidate for field effect transistors, photodetectors, catalysis, and sensors. Finally, this review is concluded with the existing challenges and a future perspective for these rising 2D NTMDs. Structure of 2D NTM...
