Description
We offer the world's largest size commercially available PdSe2 vdW crystals that measure ~5mm in size. Our cystals are grown using 6N purity precursors using flux growth to ensure purity and material quality.

Bulk PdSe2 (palladium diselenide) has been predicted to exhibit 30 meV band gap which increases to 1.43 eV indirect gap (theoretical). It has also been shown to exhibit superconductivity below ~13K under mild hydrostatic pressures, and even semimetallic response in the bulk form. In comparison to other TMDCs, PdSe2 has an uncommon structure: Pd atoms coordinate with four Se atoms, forming a square backbone lattice. It has also been recently shown that PdSe2 monolayer immediately undergo PdSe2 to Pd2Se3 crystal transformation. Owing to vast amount of Pd atoms, PdSe2 has been theoretically and experimentally shown to be catalytically active material thoigh fundamental research still remains at its seminal stages. The product measures near ~5mm in overall size and contains a few pieces in each order.
