Morphological Regulation on Barium Titanate Perovskite Particles for Broadening Microwave Absorption in GHz and THz Range

Key Points

• To explore how different morphologies of barium titanate affect microwave absorption capabilities in GHz and THz frequencies.
• Two-step hydrothermal synthesis to produce barium titanate crystals
• Four distinct morphologies created: spherical, rod-like, platelet-like, and blocky
• Characterization of absorption properties across GHz and THz ranges
• Different morphologies exhibited varying degrees of microwave absorption
• Rod-like particles showed the highest absorption efficiency in the GHz range
• Platelet-like morphology enhanced absorption in the THz range
