Nb₀.₉₅Ti₀.₀₅Se₂ (4Hb phase, Ti-doped NbSe₂)

Nb_0.95Ti_0.05Se₂ (4Hb phase) is a titanium-doped 4Hb-polytype niobium diselenide: a metal with superconductivity at T_c ~ 3.3 K. Ti substitution tunes the carrier density and disorder of the parent NbSe₂, providing a controlled platform for studying superconductivity and charge order in doped transition-metal dichalcogenides.

Growth method: Chemical vapor transport (CVT).

Specifications: Plate-like crystals, approximately 1 mm × 1 mm × 0.1 mm (l × w × t). Multiple pieces per pack.

Exfoliation difficulty: Moderate (van der Waals layered crystal).
