A wafer-scale two-dimensional platinum monosulfide ultrathin film via metal sulfurization for high performance photoelectronics

Abstract

2D nonlayered materials have attracted enormous research interests due to their novel physical and chemical properties with the confined dimensions. Platinum sulfide as one of the most common platinum-group minerals...

Applications of MXenes in human-like sensors and actuators

“…Cheng et al report an MXene/Si-based image sensor array with a high resolution of 2 μm [140]. The Ti 3 C 2 T x /Si photodetector has a high-density integrated array of 1,024 pixels (Fig.…”

“…With a transistor-based detector in each pixel, the MXene/Si image sensor [140] has been fabricated with conventional lithography protocols over a 4-inch wafer, which shows high compatibility with Si technology. The MXene stacking with other photosensitive materials, such as metal sulfides [141][142][143] or selenides [144][145][146], leads to the regulation of detection wavelength.…”

Dopant‐free passivating contacts for crystalline silicon solar cells: Progress and prospects

“…Another small group of CTL materials is low‐dimensional materials. Following the discovery of graphene and the rapid development of related low‐dimensional materials, including carbon nanotubes (CNTs), MoS 2 , WSe 2 , and so forth, a series of major achievements have been established in electronics and optoelectronics 133–137 . Many research teams have thus attempted to apply these materials in the PV field, but the results so far are not encouraging 138–143 .…”

“…Following the discovery of graphene and the rapid development of related lowdimensional materials, including carbon nanotubes (CNTs), MoS 2 , WSe 2 , and so forth, a series of major achievements have been established in electronics and optoelectronics. [133][134][135][136][137] Many research teams have thus attempted to apply these materials in the PV field, but the results so far are not encouraging. [138][139][140][141][142][143] For example, theory predicts that the separation of photogenerated carriers could be facilitated by the built-in electric field at the monolayer MoS 2 /c-Si interface.…”

A mini-review focusing on ambient-pressure chemical vapor deposition (AP-CVD) based synthesis of layered transition metal selenides for energy storage applications

“…The novel discovery of graphene in 2004 and its successful implementation since then has paved a pathway for 2D layered materials, which exhibit unique properties. 1–10 Among the many layered materials, transition metal dichalcogenides (TMDCs) with an X–M–X structure (M: transition metal element; X: S, Se, or Te) have the utmost growing potential for application in energy storage, catalysis, gas sensing, nanophotonics, etc. 11–18…”
