When the bulk phonon dispersion is ignored, the optical phonon modes in QD can be clearly divided into the confined LO- and TO-bulk-like modes and the extended interface-like modes. Among the interface-like modes, a special attention is given to the corner modes, whose anisotropic behavior ...
IR spectroscopy as a complementary technique has been used in order to completely describe the phonon modes ofr-BS. All experimentally observed bands have been compared with theoretically calculated ones and modes assignment has been performed.r-BS enriched by10B isotope was synthesized, and the ...

The equation of motion for the p-polarization field in an arbitrary wurtzite multilayer heterostructure is solved for the propagating optical-phonon (POP) modes in the framework of the dielectric-continuum model and Loudon's uniaxial crystal model. The polarization eigenvector, the dispersion relation...
Naturally we would like to find corresponding optical phonon modes in ice. As shown inFig. 1the dielectric spectra and LO–TO splitting of supercooled water resembles that of ice. Recently evidence has been presented for propagating librational phonon modes in ice XI (refs42,43). Three of the...

Optically active phonon modes in ferroelectrics such as potassium titanyl phosphate (KTP) and potassium titanyl arsenate (KTA) in the ~7鈥 20THz range play an important role in applications of these materials in Raman lasing and terahertz wave generation. Previous studies with picosecond pulse ...
