Raman scattering study of InAs nanowires under high pressure.
The pressure-dependent phonon modes of InAs nanowires have been investigated by Raman spectroscopy under high pressure up to ∼58 GPa. X-ray diffraction measurements show that InAs nanowires at 21 GPa exhibit a phase transition from a wurtzite to an orthorhombic crystal structure, with a corresponding drastic change in the first-order Raman spectra. In the low-pressure regime, a linear increase ...
متن کاملRaman spectra of CdTe/ZnTe self-assembled quantum dots
In this paper we present Raman scattering and photoluminescence spectra measured on CdTe/ZnTe self assembled quantum dots. The photoluminescence spectrum has shown two main emission peaks, both connected with existing of quantum dots. One presents direct deexcitation to ground state and the other is optical phonon (ω = 207.3 cm−1)-assisted deexcitation. The registered multiphonon emission proce...
متن کاملEffect of end groups on the raman spectra of lycopene and β-carotene under high pressure.
The Raman spectra of all-trans-lycopene in n-hexane were measured under high pressure, and the results compared with those of β-carotene. The different pressure effects on Raman spectra are analyzed taking into account the different structures of lycopene and β-carotene molecules. It is concluded that: (a) the vibronic coupling between the S₁ and S₀ states of β-carotene is stronger than that of...
متن کاملRaman Spectra of a PMMA Microstructured Optical Fibre and Direct Measurement of Its Gain Coefficient
A polymethylmethacrylate (PMMA) microstructured polymer optical fiber (mPOF) is fabricated and characterized. Using the cut-back technique the fiber loss is measured which is higher than the step-index silica fibers. Through a novel experimental scheme, the backward Stokes spectrum of the fabricated mPOF is recorded over a range exceeding 3000 cm‑1 during the cut-back method and compared ...
متن کاملEffect of pressure on the Raman anomaly of zinc-blende CuBr and Raman spectra of high-pressure phases
Raman spectra of isotopically pure CuBr (Cu Br) were measured under hydrostatic pressures up to 10 GPa at 10 K. The anomalous line shape of the longitudinal-optic ~LO! scattering in the zinc-blende phase ~CuBr-III, 0–4 GPa!, consisting of a broad structure between 155 and 177 cm, exhibits a continuous change with pressure and develops into a narrow LO phonon peak near 4 GPa. The disappearance o...
