This review discusses how low-energy valence excitations created by swift electrons can
render information on the optical response of structured materials with unmatched spatial …

Cathodoluminescence spectroscopy (CL) allows characterizing light emission in bulk and
nanostructured materials and is a key tool in fields ranging from materials science to …

We present a method to separate coherent and incoherent contributions to
cathodoluminescence from bulk materials by using angle-resolved cathodoluminescence …

Over the last five decades, the isotope effect in solids has been one of the major researches
in solid state science. Most of the physical properties of a solid depend to a greater or lesser …

We review our recent results on properties of high quality B‐doped homoepitaxial diamond
thin films grown by chemical vapor deposition (CVD) by using trimethylboron (TMB) as a B …

We have investigated fine structure splitting of indirect excitons in ultrapure diamond by high-
resolution spectroscopy. The role of the mass-anisotropy splitting has been revealed by …

Since the research on diamond doping remains an issue for electronic applications, the
luminescence spectroscopy of bound excitons appears essential to evaluate the properties …

Ultrafine splittings are found in the optical absorption spectra of boron-doped diamond
measured with high resolution. An analytical model of an exciton complex is developed …

In this study, the exciton binding energies of AlN are calculated by the anisotropic effective
mass theory, which considers the strong electron–hole exchange and Fröhlich-type exciton …

Over the last five decades, the isotope effect has been one of the major research in solids.
Most of the physical properties of a solid depend to a greater or lesser degree on its isotopic …
