Aluminum (Al) Single Crystal Substrates

Description

Aluminum (Al) single crystals are high-purity metallic substrates featuring an ordered atomic structure throughout the entire specimen. With a face-centered cubic (FCC) crystal structure and excellent ductility, thermal conductivity, and corrosion resistance, Aluminum single crystals are widely utilized in surface science research, epitaxial growth studies, and advanced material development. Their well-defined crystallographic orientation provides a stable platform for fundamental studies of surface reactions, catalytic behavior, and thin-film deposition.

Crystal Structure and Orientation:

• Crystal System: Face-Centered Cubic (FCC)
• Space Group: Fm-3m (No. 225)
• Lattice Constant: a = 4.0495 Å
• Density: 2.70 g/cm³
• Surface Orientations Available:
  • (100)
  • (110)
  • (111)
  • Custom orientations (e.g., (210), (311), etc.) upon request

Precise orientation control (within ±0.5° or better) ensures consistent performance in research and epitaxial applications.

Key Properties and Advantages:

• Excellent Surface Flatness: Atomically smooth surfaces after mechanical and chemical polishing
• Superior Purity: Available with purity grades ≥ 99.999% (5N) for high-precision applications
• Outstanding Thermal Conductivity: ~235 W/m·K at 300K
• High Ductility and Malleability: Ideal for deformation and recrystallization studies
• Stable Oxide Layer: Natural formation of a thin Al₂O₃ protective layer
• Corrosion Resistance: Suitable for atmospheric and mild chemical environments
• Customizable Size and Thickness: From small squares to large diameter disks

Typical Applications:

• Surface science and atomic-scale surface studies
• Epitaxial growth substrate for metals and thin films
• Catalysis research, including oxidation and adsorption studies
• Material deformation and dislocation dynamics research
• Calibration standards for electron microscopy and X-ray diffraction
• Nano-fabrication and MEMS applications
• Sensor and microelectronic device research
