Synthesis and characterisation of thin-film platinum disulfide and platinum sulfide

Abstract

Group-10 transition metal dichalcogenides (TMDs) are rising in prominence within the highly innovative field of 2D materials. While PtS2 has been investigated for potential electronic applications, due to its high...

The Role of Additives in Suppressing the Degradation of Liquid‐Exfoliated WS2 Monolayers

“…This is due to the fact that WS 2 is resonantly excited in Raman spectroscopy in contrast to oxides as described recently for TMDs elsewhere. [ 40 ]…”

Exciton‐Like and Mid‐Gap Absorption Dynamics of PtS in Resonant and Transparent Regions

“…The PtS film in this work, with an initial Pt thickness of 5 nm, was synthesized through the TAC process, [10,19] which is a common method for uniform, large-scale, and cost-effective production of thin films of 2D materials, such as MoS 2 , [21,22] WS 2 , [23] PtSe 2 , [24,25] PtS 2 , [10] etc. In this method, the morphology of the synthesized transition metal dichalcogenides (TMDs) is usually influenced by the initial thickness and quantity of the precursor metal.…”

“…[7] Unexpected electronic field shift was recently noted by Harms et al when they employed a high resolution intracavity laser spectroscopy. [8] Although efforts and progress on comprehending the properties of PtS have been ongoing, they thus far mainly concentrated upon the structure and synthesis, [5][6][7][9][10][11] the electrical properties, [11][12][13][14][15] and a few on the optical properties including our latest work on optical nonlinearity and ultrafast optics aspects from the bulk to their 2D form. [16][17][18][19] The global optical property of PtS, however, is still suffering a significant knowledge gap.…”

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

“…The Raman spectrum shows a peak at around 325 cm −1 , which corresponds to the B 1g mode of PtS. 19 Further scanning transmission electron microscope (STEM) images show the structure of PtS with [001] and [021] orientations (discussed later in Fig. 2).…”

“…10–12 Platinum sulfide has shown extraordinary mechanical, 13,14 optical, electronic, magnetic 15 and phase transition properties. 16 A few reports on 2D PtS exist including electronic structure calculations, 17,18 spectral analysis 19 and nonlinear optical device applications. 20 Besides, 2D PtS has been recently integrated into van der Waals heterostructures 21 for enhancing the device performances.…”
