HfSe2 Hafnium Selenide Crystal 99.995% ~8mm ATOMFAIR®

HfSe2 (Hafnium Selenide) layered crystal at 99.995% purity and ~8mm size offers high-purity transition metal dichalcogenide material for fundamental 2D materials research, but the fixed ~8mm crystal size and box packaging impose constraints on sample geometry and handling for device fabrication.

Positive

• High purity 99.995%: The 99.995% purity level minimizes extrinsic dopants and defects, critical for reproducible electronic transport and optical measurements in 2D material exfoliation studies.
• Layered crystal morphology: The layered crystal structure of HfSe2 enables mechanical exfoliation to produce atomically thin flakes for van der Waals heterostructure and quantum confinement experiments.

Trade-offs

• Fixed ~8mm crystal size: The ~8mm crystal size limits the maximum exfoliated flake area and may not suit applications requiring larger continuous single-crystal domains for device arrays.
• Box packaging constraints: The box packaging provides no controlled atmosphere or moisture barrier, requiring immediate transfer to an inert environment to prevent surface oxidation or degradation of the air-sensitive selenide crystal.
