“…In addition, when the carbon content is varied from 41.8% to 68.7%, the grain size would decrease monotonically from 40.6 to 3.9 nm [114]. Molybdenum carbide film has also been grown by radio frequency magnetron sputtering by using Mo 2 C target, and its application in the generation of solid-state passive Q-switched pulsed lasers has been studied [117]. At 1064 and 1342 nm, the Mo 2 C films show a large nonlinear saturated absorption, and the modulation depth is 10.39% and 8.89%, respectively, suggesting a well broadband nonlinear optical application.…”

As a new member in two-dimensional materials family, transition metal carbides (TMCs) have many excellent properties, such as chemical stability, in-plane anisotropy, high conductivity and flexibility, and remarkable energy conversation efficiency, which predispose them for promising applications as transparent electrode, flexible electronics, broadband photodetectors and battery electrodes. However, up to now, their device applications are in the early stage, especially because their controllable synthesis is still a great challenge. This review systematically summarized the state-of-the-art research in this rapidly developing field with particular focus on structure, property, synthesis and applicability of TMCs. Finally, the current challenges and future perspectives are outlined for the application of 2D TMCs.

The atomic layer technique is generating a lot of excitement and study due to its profound physics and enormous potential in device fabrication. This article reviews current developments in atomic layer technology for spintronics, including atomic layer deposition (ALD) and atomic layer etching (ALE). To begin, we introduce the main atomic layer deposition techniques. Then, in a brief review, we discuss ALE technology for insulators, semiconductors, metals, and newly created two-dimensional van der Waals materials. Additionally, we compare the critical factors learned from ALD to constructing ALE technology. Finally, we discuss the future prospects and challenges of atomic layer technology in the field of spinronics.

“…From the articles mentioned above, on the other hand, it is seen that SAs are core devices to sharpen the pulse in the temporal domain, and the research on various new SAs has greatly promoted the development of pulsed lasers in the last decade. Except for the traditional semiconductor saturable absorber mirrors (SESAMs), two-dimensional (2D) materials [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ], quantum dots [ 28 , 29 ], metal nanoparticles [ 30 , 31 , 32 , 33 ], and other new SAs have been intensively studied. Furthermore, after graphene was found to have saturable absorption properties and used as SA for mode-locked lasers in 2009 [ 34 ], a wide range of 2D materials such as transition metal dichalcogenides (TMDs) [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ], topological insulators (TIs) [ 19 , 20 , 21 , 22 ], black phosphorus (BP) [ 23 , 24 ], MXenes [ 25 , 26 , 27 ], were shown to have great potential in the construction of high-performance and new functional optoelectronic devices [ 1 , 2 , 3 , 4 , 5 ,…”

Large-energy mode-locked fiber lasers are extensively studied due to their indispensable use in various fields and applications. Recently, ferromagnetic insulators have attracted tremendous research interest in ultra-fast photonics because of their unique ferromagnetic properties and typical layered structure. In our work, Cr2Si2Te6 nanosheets are prepared and utilized as a saturable absorber (SA) in a large-energy mode-locked erbium-doped fiber (EDF) laser. With a total cavity length of 240 m, a stable mode-locked operation characterized by maximum pulse energy as high as 244.76 nJ with a repetition rate of 847.64 kHz is achieved. When the cavity length is extended to 390 m, the output maximum pulse energy is successfully scaled up to 325.50 nJ. To our knowledge, this is the largest pulse energy and highest output power level to be achieved in mode-locked fiber lasers by two-dimensional (2D) material saturable absorbers (SAs) so far. This work not only makes a forward step to the investigation of the generation of large-energy pulses in mode-locked fiber lasers but also fully proves that the ferromagnetic insulator-Cr2Si2Te6 possesses an excellent nonlinear absorption property, antioxidant capacity in ambient conditions, as well as outstanding thermal stability, which enriches our insight into 2D materials.
