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...
Magneto-acoustic coupling has proved an interesting approach to generate spin waves, the magnetic excitations that could encode information in new components. Until now, the role of magnetic hysteresis – i.e. the fact that the...
Converting magnetic excitation into electrical energy is of great interest for medical applications, such as remote implant charging. In a previous article, members of INSP showed that a Ni/LiNbO3/Ni composite produces a strong magnetoelectric...
X-ray photoemission spectroscopy (XPS) is a major technique in material science and nanoscience. Beyond its capability to identify elements and their chemical environments, it allows getting stoichiometries through core level peak areas. However, this...
Analysing nanoparticles with optical microscopy is a challenge: indeed, those nanoparticles are 10 times smaller than the theoretical resolution of any microscope, the diffraction limit. This limit is around 300 nm in our case....
Certain topological defects manifest as singularities or «nodes» in a phase field and are characterized by a winding number. A edge dislocation, is a typical example of such a defect, observed across a range...
