Dependence of the Excitation Energies of Boron in Diamond on Isotopic Mass
M. Cardona
Kim et al. have reported a dependence of the infrared excitation energies of boron acceptors in diamond on the isotopic mass of the carbon atoms. We show that this change can be qu…

In-plane polarized collective modes in detwinned YBaCuO observed by spectral ellipsometry
C. Bernhard, T. Holden, J. Humlíček +8
The in-plane dielectric response of detwinned YBaCuO has been studied by far-infared ellipsometry. A surprisingly lare number of in-plane polarized modes are o…

Disorder-induced phonon self-energy of semiconductors with binary isotopic composition
F. Widulle, J. Serrano, M. Cardona
Self-energy effects of Raman phonons in isotopically disordered semiconductors are deduced by perturbation theory and compared to experimental data. In contrast to the acoustic fre…
