The metal-insulator transition (MIT) in vanadium dioxide (VO2) thin films is strongly affected by grain size, thickness, and interfacial properties. Typically, a minimum thickness around 50 nm required for VO2 to exhibit significant MIT when functional substrates like sapphire silicon are used. Several works have shown that below 20 nm, with up 2-3 decades of change the resistance across MIT, can be achieved but require complex pre- or postprocessing samples. We show predeposition substrate condition control facilitates direct growth ultrathin 15 films, exhibiting between 3 4 MIT. Our findings indicate interface film crucial determining initial layers structural evolution. With appropriate surface treatment, desired enhanced regardless crystallographic orientation. Moreover, we propose novel approach obtain large changes incorporating predeposited 1.5 oxide buffer layer, thereby eliminating need use different materials also demonstrate this method improves 25-50 on substrates. study reveals simple which commonly accepted unattainable over technological importance, such as silicon.

Polyoxometalates (POMs) are molecular nano-oxides of early transition metals. As oxides, they endowed with remarkable redox properties, combining the reducibility bulk metal oxides and high versatility species. They undergo successive, reversible, highly adjustable mono- (or multi-) electronic reduction processes within a narrow range potentials. Furthermore, POMs polyanions, counter cations playing crucial role, beyond ensuring charge neutrality. missing link between extended commonly found in microelectronics, conventional organic or organometallic molecules, have attracted ever-increasing interest field nanoelectronics. hold promise as storage nodes multilevel nonvolatile memories resistive switching devices, areas currently boosted by development neuromorphic computing. In this context, we been exploring various strategies to immobilize onto electrodes aim improving control molecules/electrode interface. We investigating electron transport properties across POM-based nanojunctions establish relationships among POM structure, devices (e.g., conductance, switching). Additionally, demonstrated that can commute state layer exposure light applying an electric field, opening up new opportunities stimuli-responsive devices.
