    HOPG (Highly Oriented Pyrolytic Graphite) Sheets

    Research Grade – ZYA / ZYB / ZYB-1
    Highly Oriented Pyrolytic Graphite (HOPG) is a synthetic graphite crystal with extremely high crystallographic alignment along the c-axis. It is widely used as a standard substrate for surface science, STM/AFM imaging, graphene exfoliation, and thin film deposition.
    HOPG provides atomically flat surfaces after mechanical cleavage, making it one of the most reliable reference materials for nanoscale and electronic studies.

    Key Features
    – Extremely low mosaic spread (down to 0.4°)
    – Atomically smooth surface after cleaving
    – High in-plane electrical conductivity
    – Excellent crystallographic orientation
    – Repeatedly cleavable for fresh surfaces
    – Ideal substrate for graphene exfoliation

    Available Grades
    ZYA Grade (Premium Research Grade)
    Mosaic Spread: 0.4° ± 0.1°
    Highest crystallographic alignment
    Suitable for:
    High-resolution STM
    Surface physics research
    Epitaxial growth
    Precision graphene studies

    ZYB Grade (Standard Research Grade)
    Mosaic Spread: 0.8° ± 0.2°
    Excellent for general laboratory use
    Suitable for:
    Routine STM/AFM

    Why Choose High-Grade HOPG?
    Lower mosaic spread means:
    Better crystallographic alignment
    Larger single-domain regions
    Improved surface flatness
    Higher experimental reproducibility
    For high-resolution research, ZYA grade (0.4°) is recommended.
