High energy barriers for edge dislocation motion in body-centered cubic high entropy alloys

William Curtin, Recep Ekin Kubilay, Francesco Maresca, Alireza Ghafarollahi

Recent theory proposes that edge dislocations in random body-centered cubic (BCC) high entropy alloys have high barriers for motion, conveying high strengths up to high temperatures. Here, the energy barriers for edge motion are computed for two model allo ...

No money, no honey? Financial versus knowledge and demand constraints on innovation

Gabriele Pellegrino

The paper adds to the literature on the barriers to innovation in two ways. First, we assess comparatively what mostly constrains firms' ability to translate investment in innovation activity into new products and processes, whether it is mainly finance, a ...

Non-Linear Gyrokinetic Simulations of Microturbulence in TCV Electron Internal Transport Barriers

Olivier Sauter, Laurent Villard, Stephan Brunner, Emiliano Fable, Xavier Lapillonne

Using the local (flux-tube) version of the Eulerian code GENE (Jenko et al 2000 Phys. Plasmas 7 1904), gyrokinetic simulations of microturbulence were carried out considering parameters relevant to electron-internal transport barriers (e-ITBs) in the TCV t ...

Light engineering of the polariton landscape in semiconductor microcavities

Romuald Houdré, Cristiano Ciuti

We demonstrate a method to create potential barriers with polarized light beams for polaritons in semiconductor microcavities. The form of the barriers is engineered via the real space shape of a focalized beam on the sample. Their height can be determined ...

Competition between excitons and exciplexes: Experiments on multilayered organic light emitting diodes

Detlef Berner, Mauro Castellani

The electronic processes responsible for charge transport and electroluminescence in multilayered organic light emitting diodes (OLEDs) are very sensitive to the properties of the organic heterojunction. In particular, the height of the energy barrier affe ...
