Multiple-excitation study of the double-resonance Raman bands in rhombohedral graphite
Sergio L. L. M. Ramos, Marcos A. Pimenta, Ana Champi
The double-resonance (DR) Raman process is a signature of all sp2 carbon material and provide fundamental information of the electronic structure and phonon dispersion in graphene,…
Interplay between organic cations and inorganic framework and incommensurability in hybrid lead-halide perovskite CH3NH3PbBr3
Yinsheng Guo, Omer Yaffe, Daniel W. Paley +6
Organic-inorganic coupling in the hybrid lead-halide perovskite is a central issue in rationalizing the outstanding photovoltaic performance of these emerging materials. Here we co…
Edge phonons in black phosphorus
H. B. Ribeiro, C. E. P. Villegas, D. A. Bahamon +6
Exfoliated black phosphorus has recently emerged as a new two-dimensional crystal that, due to its peculiar and anisotropic crystalline and electronic band structures, may have pot…
Local polar fluctuations in lead halide perovskite crystals
Omer Yaffe, Yinsheng Guo, Liang Z. Tan +11
Hybrid lead-halide perovskites have emerged as an excellent class of photovoltaic materials. Recent reports suggest that the organic molecular cation is responsible for local polar…
Probing the Electronic Structure of Bilayer Graphene by Raman Scattering
L. M. Malard, J. Nilsson, D. C. Elias +5
The electronic structure of bilayer graphene is investigated from a resonant Raman study using different laser excitation energies. The values of the parameters of the Slonczewski-…
Direct Experimental Evidence of Exciton-Phonon Bound States in Carbon Nanotubes
Flavio Plentz, Henrique B. Ribeiro, Ado Jorio +2
We present direct experimental observation of exciton-phonon bound states in the photoluminescence excitation spectra of isolated single walled carbon nanotubes in aqueous suspensi…
