We demonstrate a method to image an object using a self-probing approach based on semiconductor high-harmonic generation. On one hand, ptychography enables high-resolution imaging from the coherent light diffracted by an object. On the other hand, hi

Resolving the Dirac Cone on the Surface of Bi2Te3 Topological Insulator Nanowires by Field-Effect Measurements

Autor: Gooth, Johannes, Hamdou, Bacel, Dorn, August, Zierold, Robert, Nielsch, Kornelius

We validate the linear dispersion relation and resolve the Dirac cone on the surface of a single Bi2Te3 nanowire via a combination of field-effect and magnetoresistance measurements by which we unambiguously prove the topological insulator nature of

International audience; High-order harmonic generation (HHG) from crystals is emerging as a new ultrashort source of coherent extreme ultraviolet (XUV) light. Doping the crystal structure can offer a new way to control the source properties. Here, we

The study of the corrosion inhibition of aluminum in Na2CO3 by the Ricinus communis oil was carried out by the two methods of polarization and impedance. Ricinus communis oil ensures an efficiency of 86.83% for the addition of 1600 ppm. Analysis of t
