Multidimensional Photoemission Spectroscopy of 1T-TiTe2 for Different Crystal Orientations

Extreme ultraviolet (21.7 eV) multidimensional angle-resolved photoemission spectroscopy data isolates the role of orbital texture in photoemission from the transition metal dichalcogenide 1T-TiTe2. The dataset compares experimental results from two mirror-symmetric crystal orientations with theoretical calculations from a quantitative one-step model and a tight-binding model. Samuel Beaulieu of the Centre National de la Recherche Scientifique authored this research, which demonstrates the link between momentum-dependent orbital orientation and intrinsic linear dichroism.

Use Cases

• Validate theoretical photoemission models based on experimental multidimensional spectroscopy data.
• Study the effect of crystal orientation and orbital texture on photoelectron angular distributions.
• Analyze intrinsic linear dichroism in transition metal dichalcogenides.
• Compare one-step model calculations with tight-binding model predictions for photoemission.

Strengths

• Data is linked to theoretical calculations from both a quantitative one-step model and an intuitive tight-binding model.
• Experimental results are from two distinct crystal orientations linked by mirror symmetry, enabling comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
