Title: Reconfigurable Vanadium Dioxide Nanomembranes and Microtubes with Controllable Phase Transition Temperatures

Abstract

Here, two additional structural forms, free-standing nanomembranes and microtubes, are reported and added to the vanadium dioxide (VO ₂) material family. Free-standing VO ₂ nanomembranes were fabricated by precisely thinning as-grown VO ₂ thin films and etching away the sacrificial layer underneath. VO ₂ microtubes with a range of controllable diameters were rolled-up from the VO ₂ nanomembranes. When a VO ₂ nanomembrane is rolled-up into a microtubular structure, a significant compressive strain is generated and accommodated therein, which decreases the phase transition temperature of the VO ₂ material. The magnitude of the compressive strain is determined by the curvature of the VO ₂ microtube, which can be rationally and accurately designed by controlling the tube diameter during the rolling-up fabrication process. The VO ₂ microtube rolling-up process presents a novel way to controllably tune the phase transition temperature of VO ₂ materials over a wide range toward practical applications. Furthermore, the rolling-up process is reversible. A VO ₂ microtube can be transformed back into a nanomembrane by introducing an external strain. Because of its tunable phase transition temperature and reversible shape transformation, the VO ₂ nanomembrane-microtube structure is promising for device applications. As an example application, a tubular microactuatormore »« less

Electrochemically Triggered Metal-Insulator Transition between VO ₂ and V ₂O ₅

Journal Article Lu, Qiyang ; Bishop, Sean R. ; Lee, Dongkyu ; ... - Advanced Functional Materials

Distinct properties of multiple phases of vanadium oxide (VO _x) render this material family attractive for advanced electronic devices, catalysis, and energy storage. In this work, phase boundaries of VO _x are crossed and distinct electronic properties are obtained by electrochemically tuning the oxygen content of VO _x thin films under a wide range of temperatures. Reversible phase transitions between two adjacent VO _x phases, VO ₂ and V ₂O ₅, are obtained. Cathodic biases trigger the phase transition from V ₂O ₅ to VO ₂, accompanied by disappearance of the wide band gap. The transformed phase is stable uponmore »« less

Enhanced axial confinement in a monolithically integrated self-rolled-up SiN _x vertical microring photonic coupler

Journal Article Yu, Xin ; Goddard, Lynford L. ; Li, Xiuling ; ... - Applied Physics Letters

We report an efficient method to introduce enhanced axial confinement in the self-rolled-up SiN _x vertical microtube coupler by depositing a thin layer of high refractive index material strip within the coupling section and effectively forming a vertical microring. Three times wider mode spacing is observed in such a vertical microring coupler monolithically integrated with a silicon nitride ridge waveguide as compared to the one without such axial confinement. More importantly, single mode operation within the telecomm C-band and S-band is achieved. The self-rolled-up microtube has been demonstrated to be a versatile device platform, which has found application in amore »« less

Electrical Transition in Isostructural VO ₂ Thin-Film Heterostructures

Journal Article Moatti, Adele ; Sachan, Ritesh ; Cooper, Valentino R. ; ... - Scientific Reports

Control over the concurrent occurrence of structural (monoclinic to tetragonal) and electrical (insulator to the conductor) transitions presents a formidable challenge for VO ₂-based thin film devices. Speed, lifetime, and reliability of these devices can be significantly improved by utilizing solely electrical transition while eliminating structural transition. We design a novel strain-stabilized isostructural VO ₂ epitaxial thin-film system where the electrical transition occurs without any observable structural transition. The thin-film heterostructures with a completely relaxed NiO buffer layer have been synthesized allowing complete control over strains in VO ₂ films. The strain trapping in VO ₂ thin films occurs belowmore »« less

Self-Assembled, Nanostructured, Tunable Metamaterials via Spinodal Decomposition

Journal Article Chen, Zuhuang ; Wang, Xi ; Qi, Yajun ; ... - ACS Nano

Self-assembly via nanoscale phase separation offers an elegant route to fabricate nanocomposites with physical properties unattainable in single-component systems. One important class of nanocomposites are optical metamaterials which exhibit exotic properties and lead to opportunities for agile control of light propagation. Such metamaterials are typically fabricated via expensive and hard-to-scale top-down processes requiring precise integration of dissimilar materials. In turn, there is a need for alternative, more efficient routes to fabricate large-scale metamaterials for practical applications with deep-subwave length resolution. Here, we demonstrate a bottom-up approach to fabricate scalable nanostructured metamaterials via spinodal decomposition. To demonstrate the potential of suchmore »« less

Irreversible metal-insulator transition in thin film VO ₂ induced by soft X-ray irradiation

Journal Article Singh, V. R. ; Jovic, V. ; Valmianski, I. ; ... - Applied Physics Letters

In this study, we show the ability of soft x-ray irradiation to induce room temperature metal-insulator transitions (MITs) in VO ₂ thin films grown on R-plane sapphire. The ability of soft x-rays to induce MIT in VO ₂ thin films is confirmed by photoemission spectroscopy and soft x-ray spectroscopy measurements. When irradiation was discontinued, the systems do not return to the insulating phase. Analysis of valence band photoemission spectra revealed that the density of states (DOSs) of the V 3d band increased with irradiation time, while the DOS of the O 2p band decreased. We use these results to proposemore »« less
