Molecularly-induced roughness and oxidation in cobalt/organodithiol/cobalt nanolayers synthesized by sputter-deposition and molecular sublimation

Abstract

Integrating interfacial molecular nanolayers (MNL) with inorganic nanolayers is of interest for understanding processing-structure/chemistry correlations in hybrid nanolaminates. Here, we report the synthesis of Co/biphenyldithiol(BPDT)/Co nanolayer sandwiches by metal sputter-deposition...

Nanomolecularly-induced Effects at Titania/Organo-Diphosphonate Interfaces for Stable Hybrid Multilayers with Emergent Properties

“…Metal-oxide-based hybrid thin film multilayers have been fabricated by sequential atomic layer deposition (ALD) and molecular layer deposition (MLD). Such nanolaminates exhibit unusual property combinations different from that of the constituent materials, e.g., high electrical and low thermal conductivities, , and mechanical flexibility. , However, very little is known about the effects of the MNL structure and chemistry on the nano/micro-scale structure, morphology, and phase stability of inorganic nanolayers, as well as the inorganic/MNL interfaces …”

“…16,17 However, very little is known about the effects of the MNL structure and chemistry on the nano/micro-scale structure, morphology, and phase stability of inorganic nanolayers, as well as the inorganic/ MNL interfaces. 18 Here, we report the synthesis of titania/organophosphate-MNL multilayers (see Scheme in Figure 1) and describe MNLinduced decreases in the titania nanolayer growth rate, suppression of anatase nanocrystal formation, and increases in surface roughness. We show that these phenomena are related to the MNL structure, bonding chemistry, and impurity incorporation during titania growth.…”
