Fano resonances cause the loss of symmetrical line shape, leading to a nonsymmetrical signature shape. Fano resonance is the result of a purely quantum process, with the coupling between external perturbation, discrete state, and continuum states determining the degree of asymmetry (Fig. 2). The ...

Despite being applied with success in many fields of materials science, Raman spectroscopy is not yet determinant in the study of electroceramics. Recent experimental and theoretical developments, however, should increase the popularity of Raman spectros
Raman spectroscopy is an integral part of graphene research. It is used to determine the number and orientation of layers, the quality and types of edge, and the effects of perturbations, such as electric and magnetic fields, strain, doping, disorder and functional groups. This, in turn, prov...
These results demonstrate a strong sensitivity to sample preparation that is important for both a fundamental understanding of these novel materials as well as reliable reproduction of device properties. The novel properties of graphene have stimulated research in other two-dimensional (2D) materials ...
Raman spectroscopy is frequently used to identify composition, structure and layer thickness of 2D materials. Here, we describe an efficient first-principles workflow for calculating resonant first-order Raman spectra of solids within third-order perturb
