The temperature dependence of the Raman-active mode frequencies in indium sulfide was measured in the range from 10 to 300 K. The analysis of the temperature dependence of the A(g) intralayer optical modes show that Raman frequency shift results from the change of harmonic frequency with volume expansion and anharmonic coupling to phonons of other branches. The pure-temperature contribution (phonon-phonon coupling) is due to three- and four-phonon processes.

Temperature dependence of the first-order Raman scattering in GaS layered crystals
Hasanlı, Nızamı; Ozkan, H; Kocabas, C (2000-01-01)
The temperature dependence (15-293 K) of the six Raman-active mode frequencies and linewidths in gallium sulfide has been measured in the frequency range from 15 to 380 cm(-1). We observed softening and broadening of the optical phonon lines with increasing temperature. Comparison between the experimental data and theories of the shift and broadening of the interlayer and intralayer phonon lines during the heating of the crystal showed that the experimental dependencies can be explained by the contributions...

Temperature and excitation intensity tuned photoluminescence in Ga0.75In0.25Se crystals
Isik, M.; Guler, I.; Hasanlı, Nızamı (2013-01-01)
Photoluminescence (PL) spectra of Ga0.75In0.25Se layered single crystals have been studied in the wavelength range of 580-670 nm and temperature range of 7-59 K. Two PL emission bands centered at 613 nm (2.02 eV, A-band) and 623 nm (1.99 eV, B-band) were revealed at T = 7K. The excitation laser intensity dependence of the emission bands have been studied in the 0.06-1.40 W cm(-2) range. Radiative transitions from shallow donor levels located at E-A = 0.11 and E-B = 0.15 eV below the bottom of conduction ban...
Temperature dependence of the Raman frequency of an internal mode for SiO2-moganite close to the α-β Transition
Lider, Mustafa Cem; Yurtseven, Hasan Hamit (2012-12-01)
The temperature dependence of the 501 cm frequency of the vibrational mode is analyzed for SiO moganite. The experimental data for the heating and cooling cycles of moganite from the literature is used for our analysis. The coexistence of moganite is obtained over a finite temperature interval, and the moganite transition at around 570 K is studied, as observed experimentally.
Temperature-dependent optical properties of GaSe layered single crystals
IŞIK, MEHMET; TUĞAY, EVRİN; Gasanly, N. M. (2016-01-01)
Optical properties of GaSe single crystals have been investigated using temperature-dependent transmission and room temperature reflection measurements in the wavelength range of 380-1100nm. The analysis of the absorption data at room temperature showed the existence of indirect transitions in the crystal with energy band gap of 1.98eV. Temperature dependence of the transmission measurements revealed the shift of the absorption edge toward lower energy as temperature is increased from 10 to 280K. The rate o...
