WebAug 1, 2004 · The characteristic energy of the LO phonon can be determined from the energy spacing between the exciton resonant lines and their LO phonon replicas .The LO phonon energy of ZnO crystal is ∼72 meV at low temperature, depicted as the dotted line for reference in Fig. 3 together with the three physical quantities, FXA-1LO, (FXA-2LO)/2, and … WebTemperature-dependent phonon replica characteristics in intrinsic InN nanowires have been further analyzed (Zhao et al., 2012c). Illustrated in Fig. 11 C, the PL spectral linewidth of phonon sideband emission ( Γ PSB ) becomes broader as the temperature increases while the phonon energy ( E phonon ) becomes smaller as the temperature increases.

Web1) Have you set the wavelength resolution of your PL system high enough to resolve the phonon replica? If not, you need reduce the entrance slit width or so on. 2) Sample should … Webthemselves as phonon replicas of the zero-phonon line corresponding to the impurity exciton in the absorption spectrum (Fig. 1). In order to separate the exciton con-tribution to impurity absorption and to improve the sen-sitivity of the technique, we used electric-field modula-tion. Such a technique allows high-order processes to be recorded ... how is elevation above sea level determined
