Melting—the transformation of a solid into a liquid upon heating—is the reverse of solidification. Yet, despite the apparent symmetry, melting and solidification give rise to markedly different pattern-forming phenomena. In recent years, melting of...
Colloidal nanocrystals of halide perovskites have attracted significant interest in optoelectronics due to their excellent optical properties, particularly their high quantum yields and the ability to tune their emission energies. The PHOCOS[1] team has...
Phase-change materials such as vanadium dioxide (VO2) are attracting growing interest because of their insulator–metal transition at temperatures close to room temperature. This reversible transition induces drastic changes in their electrical, optical, and thermal...
Arthropods species (insects, spiders, scorpions, etc.) account for nearly two-thirds of all living organisms on Earth. Present for hundreds of millions of years, they have adapted to absolutely every environment, especialy light environnements. From...
Glasses exhibit atypical thermomechanical properties that are very different from those of crystals. Many of these peculiarities are closely linked to the existence of the boson peak, an excess of vibrational states whose origin...
Optoelectronics is the field of material science where light–matter interaction is controlled with electronic tools, and the most preferred knob is bias. Semiconductors play a central role in this field. Here, researcher from INSP...
The reduction of molybdenum trioxide (MoO₃) profoundly modifies its structural and electronic properties, making it a material of interest for numerous technological applications, ranging from (photo-)catalysis to optoelectronics, or electrochromic devices, among others. Although...
Semiconductor-based quantum dots have demonstrated remarkable potential for quantum information applications, such as the bright emission of single and indistinguishable photons or the creation of qubits that can be initialized, manipulated, and read using...
Proton transfer caused by light excitation in small molecules represents an ideal platform for testing the limits of our understanding of many quantum phenomena. The ultrafast and inherently non-equilibrium dynamics between nuclei and electrons...
In our environment, we find many types of lamellar materials, from lamellar polymers to superimposed biological membranes and smectic liquid crystal materials. They are all governed by the same free energy expression, which generally...
