Time and momentum resolved characterization of hybrid plasmonic heterostructure Au/WSe2

Dataset attached to paper titled "Observation of Multi-Directional Energy Transfer in a Hybrid Plasmonic-Excitonic Nanostructure" with time and momentum characterization of a 2D palsmonic heterostructure formed by Au nanoislands on bulk WSe2. It contains Angle-resolved photoemission spectroscopy (ARPES) and time-resolved ARPES data (trARPES.zip); femtosecond electron diffraction (FED) data (FED.zip); optical absorption spectroscopy data (Optical_absorbance.zip) and Transmission electron microscopy micrographs (TEM.zip). For <strong>trARPES.zip</strong>, the following table reports the grid of measurements and most important parameters: <strong>Name</strong> <strong>Sample temperature (K)</strong> <strong>Pump Wavelength (nm)</strong> <strong>Pump Duration (fs)</strong> <strong>Material</strong> trARPES_Metis_002.mpes.nxs 300 800 35 Au/WSe₂ trARPES_Phoibos_Scan2124.mpes.nxs 300 800 35 WSe₂ trARPES_Phoibos_Scan2146.mpes.nxs 70 800 35 WSe₂ trARPES_Phoibos_Scan2197.mpes.nxs* 70 800 35 Au/WSe₂ trARPES_Phoibos_Scan2198.mpes.nxs* 70 800 35 Au/WSe₂ trARPES_Phoibos_Scan2212.mpes.nxs* 300 800 35 Au/WSe₂ trARPES_Phoibos_Scan2219.mpes.nxs* 300 800 35 Au/WSe₂ trARPES_Phoibos_Scan3159.mpes.nxs 300 1030 200 Au/WSe₂ trARPES_Phoibos_Scan3164.mpes.nxs** 300 1030 200 Au/WSe₂ trARPES_Phoibos_Scan3185.mpes.nxs 300 1030 200 WSe₂ *These scans are acquired with higher angular dispersion requiring separate scans for K and Sigma valleys. **Fluence scan. <strong>FED.zip</strong> contains the following subfolders: <em>Manuscript_Figure</em>: Experimental data and fit parameters depicted in Figure 4 of the main article. <em>Analysis</em>: Additional information for the FED data including: raw data descriptions (delay, power, filename and more), Matlab scripts with comments, masks and backgrounds for image processing. The <em>Static_patterns</em> subfolder contains electron diffraction patterns of pure WSe₂ flakes and Au-covered WSe₂ flakes. <strong>Optical_absorbance.zip</strong> contains the following subfolders &amp; subfiles: <em>without Au</em> &amp; <em>with Au</em> containing all the optical measurements of pristine and Au-covered WSe₂ flakes, respectively. <em>comparison_with_and_without_Au.xlsx</em> contains the analysis of the difference curves <em>manuscript_figure.txt </em>contains the data that were used in Figure 1 of the main article.
