Notably, the capacitively coupled case (purple line) shows substantially higher intensity peaks across the full spectral range, especially at positions labeled Ag, B₁g, and Al₂O₃. These peaks are associated with specific phonon modes and bonding environments, and their enhancement under capacitively coupled conditions suggests improved crystalline ordering or a higher density of Raman-active bonds.
