| Title | Data supporting "Enhancing Photoluminescence and Mobilities in WS2 Monolayers with Oleic Acid Ligands" |
| Description | The data presented supports the results shown in the article. Origin file contains folders for data sets representing each figure in publication. Each folder can be accessed via the Project Explorer. Each folder is named according to the data it contains. The first folder (Fig 1a-d, Fig.3 SI) contains photoluminescence (PL) statistics of chemically treated tungsten disulphide (WS2) and WS2 monolayer absorption spectra respectively. The second folder (Fig 2.a.-f, Fig 2a-d, Fig 6 SI) contains steady-state PL excitation series, trion emission characterization, and PL spectra of oleic acid (OA) treated WS2 on different substrates respectively. The third folder (Fig. 3a-b, Fig 4a-d SI) contains time-resolved PL data for pristine, Oleic acid and TFSI treated WS2 at the lowest laser fluence with variation in fast decay component with carrier concentration (Fig 3a-b); time-resolved PL data for all treatments with variation in slow decay component with initial carrier concentration (SI Fig 4a-d). The fourth folder (Fig 4a and SI Fig 5) contains Raman spectra of OA treated WS2 and the effect of toluene on WS2 monolayer PL. The fifth folder (Fig 4b) contains transfer characteristics of a gated WS2 transistor. The sixth folder (Fig 4c) contains the transfer characteristics of a gated WS2 transistor with detail on the difference in gradient between OA treated and untreated WS2. The seventh folder (Fig 1 SI) shows the raw excitation series PL data fitted with Gaussian curves for OA treated WS2, which were used in characterizing trion emission seen in SI figure 2. The eighth folder (Fig 7 SI) contains transfer characteristics for a TFSI treated transistor |
