In semiconductors physics the pn junction occupies a central place being the building block of device such as LEDs or photodiodes. Usually, the junction is obtained by doping semiconductors through implantation of extrinsic impurities....
Although laser ultrasound imaging is now recognized as a powerful tool for investigating elastic properties in a wide range of fields, from applications to fundamental research, a number of obstacles remain. The generation of...
The on-demand generation of entangled photons is an essential achievement leading to important applications for quantum technologies. In semiconductor quantum dots (QDs), the radiative biexciton-exciton cascade is successfully employed. Resonant two-photon excitation (TPE), coherently...
Since the first formulation of quantum mechanics, Nature has been divided into two categories: the classical world (that of tennis balls) and the quantum world of atoms and photons. The transition between the two...
In order to offset the exit from fossil fuels, the development of renewable energies is a crucial issue – coupled of course with a reduction in our energy consumption. In the field of photovoltaic...
Nano-objects have many properties that have led to applications in recent years, particularly in the field of optics. From the point of view of elasticity, these systems, whose size can go down to a...

In the last couple of decades, Magnetocaloric (MC) materials studieshave undergone major advancements paving the way to novel energy conversion applications. Among them, a rather new field of research is represented by the possibility...
When modeling matter at the atomic scale, the behavior of electrons is described by the laws of quantum mechanics, but atomic nuclei, being heavier, are often treated as classical objects, obeying Newton’s laws. This...
Nanocrystals became an essential building blocks of modern optoelectronics. In the infrared, HgTe nanocrystals are used for the fabricate cameras and LEDs. In these polycrystalline materials, hopping has often been seen as a bottleneck...
Engineering an advanced material for biomedical applications requires dealing with antagonistic requirements: it must exhibit resistance to fracture AND biodegradability, remain highly hydrated AND carry hydrophobic active substances… Moreover, the creativity of chemists is...
