Abstract

Pulsed Laser Deposition (PLD) was used to grow chromium oxides (CrOx) on MgO(100), Al2O3(0001), SrTiO3(100), LaAlO3(100), and Si(100) under different growth conditions, including substrate temperature, O2 pressure, and laser fluence. SEM, AFM and XRD measurements show that various phases of CrOx films with different morphologies could be obtained on different substrates under the same growth conditions. Half-metallic CrO2 needle-like nanostructured films were only observed on MgO(100) under a special set of conditions.

17. It should be noted that while the SEM (or AFM) images appear to show that the deposited films to be not continuous, it is not possible to determine whether their respective nanostructures are not on top of a wetting. layer of a few atoms thick (especially given their colours over the substrates). As such, the word film. is used somewhat ambiguously here, and it refers to the nanostructured overlayer that may or may not be continuous.Google Scholar
