Ta₂PdSe₆ is a quasi-one-dimensional layered transition-metal chalcogenide, metallic/semimetallic, that has recently been reported to host topologically related bands (nodal-line/topological-semimetal features) and strongly anisotropic in-plane transport, with some studies noting low-temperature superconductivity or proximity-related behavior. As a quasi-1D topological candidate, it serves as a system for studying anisotropic transport and topological states. 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: Moderate — exfoliable by mechanical exfoliation, but isolating thin flakes may require repeated cleaving or optimized methods.
