PbI₂ (Lead Iodide)

PbI₂ is a layered semiconductor with a band gap of approximately 2.3 eV. It exfoliates very easily and is also a common precursor and reference material in perovskite research.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3–4 mm, with a purity of up to 99.999% (5N), and 2–3 high-quality single-crystal pieces included in each package.

Exfoliation: Easy — readily exfoliated by mechanical cleavage into few-layer flakes.
