Traveling-wave photomixers for sub-THz and THz generation, Photomélangeurs distribués pour la génération d'onde sub-THz et THz

Charbel Tannoury

Photomixing is an optical to THz conversion technique that involves the interaction of two optical fields of different frequencies in a photoconductive material, resulting in the generation of a THz electromagnetic wave at the frequency difference between the two optical sources. One of the…, Le photomélange est une technique de conversion d'onde optique en onde THz qui implique l'interaction de deux sources optiques de fréquences différentes dans un matériau photoconducteur, ce qui entraîne la génération d'une onde électromagnétique THz à la différence de fréquence entre…

Interface Engineering of an Ultrathin Hierarchical Phosphorus-Doped MoS2/Ni3S2 Heterostructure on Nickel Foam for Efficient Water Splitting

Yuanyuan Miao, Saifei Yuan, Hao Ren, Ahmed Addad, Alexandre Barras, Pascal Roussel, Mohammed Amin, Sabine Szunerits, Rabah Boukherroub

Rationally designed structures and elements are important for the construction of effective electrocatalysts for water splitting. Herein, we developed an ultrathin hierarchical P-doped MoS2/Ni3S2 heterostructure on nickel foam (NF) by a one-pot synthesis. Owing to its optimized electronic structure…
