  • Shape: Different shapes may enhance charge transport and interaction with other materials.
  • Particle Distribution: Uniform size distribution and minimizing aggregation are important for consistent electrical properties.
  • Porosity: Porous structures may enhance specific surface area, affecting surface-molecule interactions and charge storage capabilities.
• Surface Properties
  • Functionalization: Surface modifications can improve stability, dispersibility, and interfacial properties with other materials.
  • Oxidation Resistance: Protection against oxidation and passivation is important to maintain electronic properties.
• Electrical Performance
  • Conductivity: Electrical conductivity of materials is essential for applications in conductive inks, transparent conductive films, and interconnects in integrated circuits.
• Thermal Properties
  • Thermal Stability: High thermal stability is essential to withstand processing conditions and operational environments.
  • Thermal Conductivity: Effective heat dissipation is crucial in electronic devices to avoid overheating.
