Overview

Observational analysis measured stress tensor in nitrogen-doped CVD diamond film, suggesting unique stress properties.

Key Points

  • The nitrogen-doped CVD diamond film showed compressive stress with a volume decrease of approximately 0.073%.
  • Optically detected magnetic resonance (ODMR) spectra shifts allowed evaluation of residual stress tensor components in the diamond.
  • Confocal microscopy revealed spatial variations in the stress tensor components within the diamond film.
  • Shear stress was predominantly observed in the z-direction, aligning with the film's growth direction.
