Raman tensor elements of
Christian Kranert, Chris Sturm, Rüdiger Schmidt-Grund +1
The Raman spectrum and particularly the Raman scattering intensities of monoclinic are investigated by experiment and theory. The low symmetry of $β\text{…
Dipole Analysis of the Dielectric Function of Colour Dispersive Materials: Application to Monoclinic GaO
Chris Sturm, Rüdiger Schmidt-Grund, Christian Kranert +3
We apply a generalized model for the determination and analysis of the dielectric function of optically anisotropic materials with colour dispersion to phonon modes and show that i…
The Singular Optical Axes in Biaxial Crystals and Analysis of Their Spectral Dispersion Effects in -GaO
Marius Grundmann, Chris Sturm
We classify and distinguish optically biaxial materials, which can have triclinic, monoclinic or orthorhombic crystal symmetry, by the degeneracy of the indices of refraction of th…
Dielectric tensor of monoclinic GaO single crystals in the spectral range eV
Chris Sturm, Jürgen Furthmüller, Friedhelm Bechstedt +2
The dielectric tensor of -GaO was determined by generalized spectroscopic ellipsometry in a wide spectral range from to as well as…
