TiS₂ (1T phase) (Titanium Disulfide)

A layered van der Waals transition-metal dichalcogenide with octahedral coordination, space group P3̄m1. It is a semimetal or narrow-gap semiconductor long studied as a model thermoelectric and intercalation host (notably for Li-ion batteries). Its layered structure, low thermal conductivity, and facile guest-ion intercalation make TiS₂ an important material for thermoelectric energy conversion and two-dimensional energy-storage electrodes.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3 mm, with a purity of up to 99.9999% (6N), and multiple high-quality single-crystal pieces included in each package.

Exfoliation: Easy — readily cleaved into thin flakes by standard mechanical exfoliation.
