Selenol-Capped PbS Quantum Dot Properties for Infrared Photodetectors

A dataset from DataverseNL Harvested Dataverse details the properties of lead sulfide colloidal quantum dots capped with organoselenide ligands. The data, authored by Han Wang and last updated in July 2026, includes performance metrics for quantum dot thin films and photodiodes fabricated using a thermal cleavage method. Record hole mobility and device detectivity values are reported.

Use Cases

• Modeling p-type doping effects in quantum dot films based on the described selenol-based stoichiometry control.
• Benchmarking hole mobility in PbS CQD thin films against the reported record of 0.15 cm² V⁻¹ s⁻¹.
• Designing short-wavelength infrared photodiodes based on performance metrics like 1350 nm sensitivity and 7.1×10¹² Jones detectivity.
• Investigating the relationship between ligand chemistry and carrier transport using data on benzeneselenol and other organoselenide ligands.

Strengths

• Reports a record hole mobility of 0.15 cm² V⁻¹ s⁻¹ for p-type PbS films.
• Documents photodiode performance with sensitivity up to 1350 nm, 374 kHz bandwidth, 80% external quantum efficiency, and 7.1×10¹² Jones detectivity.
• Describes a specific, reproducible fabrication method using selenol-based ligands and thermal cleavage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is in the future (2026-07-06).
