Exciton Collimation, Focusing and Trapping Using Complex Transition Metal Dichalcogenide Lateral Heterojunctions Open
Controlling the motion of neutral excitons in optically active media is a mandatory development to enable the conception of advanced circuits and devices for applications in excitronics, quantum photonics, and optoelectronics. Recently, pr…

Surface thermomigration of 2D voids Open
In a thermal gradient, surface nanostructures have been experimentally observed to move due to thermomigration. However, analytical models that describe the thermomigration force acting on surfaces are still controversial. In this work, we…

Coriolis acceleration and critical slowing-down: A quantitative laboratory experiment Open
We experimentally investigate the motion of a pendulum on a turntable. The dynamics of this conical pendulum experiment are very rich and can be studied both at the undergraduate and graduate levels. At low rotational frequency of the turn…

Shear-coupled migration of grain boundaries: the key missing link in the mechanical behavior of small-grained metals? Open
Grain size reduction is a very efficient way to block dislocation movements and therefore create very strong metals and alloys. Not only grain boundaries are known obstacles for dislocations, but when reaching nanometer dimensions, crystal…

Modeling Iron–Gold Nanoparticles Using a Dedicated Semi-Empirical Potential: Application to the Stability of Core–Shell Structures Open
Core–shell\nnanoparticles made from iron embedded in gold have a strong potential\ninterest in nanomedicine, the Au shell providing an efficient biocompatible\ncoating for the magnetic Fe core. With the aim of determining theoretically\nth…

Strain at interfaces of the <span>I</span> n <span>A</span> s/ <span>A</span> l <span>S</span> b heterostructure for quantum cascade lasers Open
Devices based on epitaxially grown multilayers can be highly sensitive to structural and chemical properties at interfaces, especially when the active zones are of nanometric size. The InAs/AlSb system is particularly sensitive to this phe…

Elastic properties of AlAs-like and InSb-like strained interfaces in [InAs/AlSb] heterostructures Open
Elastic properties of [InAs/AlSb] heterostructures coherently grown on a (001) InAs substrate are investigated by the density functional theory and compared to the prediction of the linear elasticity theory. The stress-strain curves of the…
