Progress in power electronic devices is currently accepted through the use of wide bandgap
materials (WBG). Among them, diamond is the material with the most promising …

The unique properties of diamond are responsible for its pre-eminence as a gemstone, and
give it a glamour and attraction unprecedented for any other mineral. As the first member of …

Cathodoluminescence (CL) nanoscopy is proven to be a powerful tool to explore nanoscale
optical properties, whereby free electron beams achieve a spatial resolution far beyond the …

Monolayer two-dimensional transitional metal dichalcogenides, such as MoS2, WS2, and
WSe2, are direct band gap semiconductors with large exciton binding energy. They attract …

Confinement of charge carriers in semiconductors by quantum wells is usually
accomplished with layers that vary in elemental composition, such as aluminum gallium …

We present a comprehensive Raman study of self-energy effects in isotopically tailored
silicon crystals at low temperature. Changes in the measured Raman spectra induced by …

We have measured the refractive index n of diamond for temperatures up to 925 K from
Fabry-Perot resonances in far-infrared transmission spectra. For the highest temperatures …

During the past ten years, semiconducting crystals with varying isotopic compositions have
been grown. They can be used for obtaining detailed information on their lattice dynamics …

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

Sharp absorption lines produced by hydrogen in diamond have been studied in diamonds
grown from 13 C by high-pressure, high-temperature synthesis. Analyses of the two-phonon …
