Observation of A 1(LO), E 2(high) and B 1(high) phonon modes in In x Ga 1-xN alloys with x = 0.11-0.54

　View Summary

Phonon spectra of A 1(LO), E 2(high) and B 1(high) modes were observed in a series of hexagonal In x Ga 1-xN alloy films (x = 0.11-0.54) by Raman scattering using a deep-UV laser at 266 nm for excitation. The A 1(LO) and E 2(high) modes both showed one-mode type variation with x. The B 1(high) mode, which is Raman-forbidden in ideal binary wurtzite compounds, has been first observed in In x Ga 1-xN alloy in a clear manner. Its frequency variation is in line with a theoretical prediction of one-mode type behavior. © 2012 WILEY-VCH Verlag GmbH &amp

　View Summary

We have estimated the longitudinal effective mass (m//) of electron in n-type InN films by Raman scattering. The samples were grown by MOVPE (metal organic vapor phase epitaxy) with free carrier concentration of n=6.7×1018 -9.9×1018 cm-3 according to Hall measurement. A weak Raman signal observed at ∼430 cm-1 at room temperature was sharpened and shifted to higher frequency toward the A 1(TO)-phonon mode at 447 cm-1 with increasing n. This mode was assigned to the lower branch (L-) of the longitudinal-optic-phonon-plasmon- coupled (LOPC) mode. The line shape was carefully analyzed by a semi-classical line-shape fitting analysis assuming deformation potential and electro-optic coupling mechanisms for the light scattering process. A line-shape fitting analysis was conducted by adjusting three major parameters
electron density, effective mass and plasmon damping rate. The analysis well reproduced values of electron density and mobility deduced by Hall measurement. Electron effective mass of m//*/m0 = 0.05 (±0.01) was also obtained as the best-fit parameter. The result agrees well with previous data obtained by other optical methods. © 2010 Wiley-VCH Verlag GmbH &amp

Synthesis and characterization of Mn-doped BiFeO3 nanoparticles

H. Fukumura, S. Matsui, N. Tonari, T. Nakamura, N. Hasuike, K. Nishio, T. Isshiki, H. Harima, K. Kisoda

Acta Physica Polonica A ( Polish Academy of Sciences )  116 ( 1 ) 47 - 50   2009

　View Summary

BiFeO3 is a multiferroic material showing antiferromagnetic ordering and ferroelectric behavior simultaneously. Here, Mn-doped BiFeO 3 nanoparticles were synthesized up to 10% of Mn composition by a, sol-gel process. The samples showed high crystallinity with no secondary phase up to 2% of Mn doping. A phonon peak at 1250 cm-1 in undoped BiFeO3 showed anomalous intensity enhancement in the magnetically ordered phase below TN = 643 K due to a spin-phonon coupling. This behavior was less pronounced in the Mn-doped samples, suggesting a suppression of magnetic ordering between Fe3+ spins by Mn doping.
