Calculation of the Huang-Rhys factor for F-centers

WebThe Huang-Rhys factors for the absorption and emission of light by F-centers are derived using a modified tight binding approximation. Preparatory to this calculation, explicit representations for the discreet local phonon eigenfrequency spectra are determined as functions of electron state. ... Parameter dependent forms for the Feynman ... WebD is known as the Huang-Rhys parameter, and is a dimensionless factor related to the mean square displacement 2 2 0 2 dm Dd ω == % h (6.32) It represents the strength of coupling to the nuclear degrees of freedom. Note we can write our correlation function as 2 mn nmn n Ct p=∑ μ e−−itgtω. (6.33) Here g(t) is our lineshape function coziest flannel
