New publication: Out-of-plane preferential growth of 2D molybdenum diselenide nanosheets on laser-induced periodic surface structures

Publicada el 19 junio, 2024 por agullo

In this study, we explore the morphology and orientation of molybdenum diselenide, a Van der Waals 2D material, through isothermal closed space vapor deposition on both pristine and laser-structured substrates. Laser structuring is conducted on dielectric (sapphire), semiconductor (silicon), and … Sigue leyendo →

Spatially resolved MoOx phases by laser localized oxidation of MoO2

Publicada el 20 abril, 2021 por agullo

MoO2 thin films were subjected to a laser localized oxidation process that allowed to obtain different well defined MoOx phases. In particular, spatially resolved MoO2, α-MoO3, β-MoO3, amorphous a-MoO3, and Mo4O11 regions were obtained as a function of the laser … Sigue leyendo →
