Optical phonons in layer TIInSe2 single crystals Hasanlı, Nızamı; Dzhavadov, B.M.; Melnik, N.N.; Tagirov, V.I.; Vinogradov, E.A. (Wiley, 1979-01-01)
OPTICAL PHONONS IN GAS1-XSEX LAYER MIXED-CRYSTALS Hasanlı, Nızamı; MELNIK, NN; RAGIMOV, AS (Wiley, 1983-01-01) Measurements are made of polarized Raman scattering and infrared reflection spectra of twenty two compositions of GaS1‐xSex layer mixed crystals grown by the Bridgman method. Besides the usual one‐mode and two‐mode behaviours of phonon modes, a number of more complex dependences characterized by the appearance of additional bands in the spectra of mixed crystals are observed. Their appearance is accounted for by the uncovering of the Brillouin zone due to the disturbance of the periodicity of the crystal la...
Optical polarization anisotropy in strained A-plane GaN films on R-plane sapphire Ghosh, Sandip; Misra, Pranob; Grahn, Holger T.; İmer, Muhsine Bilge; Nakamura, Shuji; DenBaars, Steven P.; Speck, James S. (Wiley, 2006-06-01) We have used polarized photoreflectance (PR) spectroscopy to study [1120]-oriented A-plane GaN films on R-plane sapphire substrates. For this type of films, the c-axis of GaN lies in the film plane. When the probe beam is polarized perpendicular to the c-axis, we observe a single feature in the PR spectrum, while two features at higher energies are observed for parallel polarization. Comparing the transition energies with the ones obtained by electronic band-structure calculations, we identify the observed ...
