Chapter 20
Wonders of Multifield Lattice Oscillation
Abstract Physical perturbation mediates material’s properties by relaxing the interatomic bonding and electron configuration in various bands. Phonon spectroscopy
probes bond relaxation or bond tranformation from one equilibrium to another under
perturbation and electron spectroscopy fingerprints bond-relaxation induced electronic configuration, which have important impact to chemistry, physics, and material engineer and science. However, extracting information from the phonon spectroscopic measurements and gaining consistent insight into the physics behind observations are still infancy compared to crystallography and surface morphology because
of lacking basic regulations. Conventional decomposition of spectral peaks or empirical simulation of spectral evolution under perturbation provide limited information
with freely adjustable parameters and debating mechanisms. The featured multifield
phonon spectrometrics aims to extracting atomistic, local, and quantitative information on the bonding and nonbonding dynamics and their correlation to performance
of a variety of substances under external perturbations.
Highlights
• Substance evolves its structures and properties when subjecting to perturbation or
reaction.
• Bond relaxation and the associated electronic energetics dictate material’s performance.
• Correlating and resolving the bond-phonon-property of a substance is a high
challenge.
• Phonon spectrometrics resolves unprecedented information and deepens the
physical insight.
