TaSe₂ (2H phase, Superconducting) (Tantalum Diselenide)

2H-TaSe₂ is a van der Waals metal combining charge-density-wave order (T_CDW ~ 100 K) with superconductivity at T_c ~ 2.5 K, a classic system for the interplay between CDW and superconductivity. This listing is the superconductivity-characterized 2H polytype batch.

Growth method: Chemical vapor transport (CVT).

Specifications: Plate-like crystals, approximately 1 mm × 1 mm × 0.05 mm (l × w × t). Multiple pieces per pack.

Exfoliation difficulty: Easy to moderate (readily exfoliated van der Waals crystal).
