Data related to "Change in charge density wave order beyond the Lifshitz transition in 2H-Ta1±δS2"
Listed in Edmond
We have studied charge density waves (CDW) in the van der Waals (vdW) compound 2H-TaS2 using angle resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) based calculations.
Description
The dataset contains ARPES data measured at the i05 beamline of the Diamond Light Source, and the ab initio phonon spectra calculated at different doping levels for 2H-TaS2 with different vdW gap. The experimental dataset consists of temperature dependent Fermi surfaces of the 2H-TaS2, the core-level spectrum of the 2H-like inclusion region in the 4Hb-TaS2, the corresponding Fermi surface.
Content of the ZIP file '2H_TaS2_Dataset_Edmond.zip': All the ARPES data files are stored as .nxs and can be processed using custom scripts or commercially available software. In the ab initio phonon spectra, the phonon frequencies are recorded as a function of momentum-transfer along the GMKG path. The files are categorically stored in different folders.

The ARPES data is stored in the folder called 'arpes'. The ab initio phonon spectra of the standard 2H-TaS2 are stored in '/dfpt/d3' and those for the elongated c-axis are stored in '/dfpt/d3p8'. The doping levels are part of the file name.
For example, a phonon spectrum at a doping level -0.1 eV is labeled 'phband_freq_ef-0p1.freq'.
