“…TeO x thin films are deposited on ITO-coated glass by pulsed laser deposition. Amorphous TeO 2 was prepared by the melt quench method and was used as a target in the deposition process [20]. KrF Laser with a wavelength of 248 nm (Compex Pro 102) at a fluence of 3 J cm −2 was pulsed onto a target.…”

In this work, we report on the observation of resistive switching in the nanocrystalline Tellurium oxide (TeOx) in ITO/TeOx/Ag device configuration. The TeOx films grown in an O2/Ar environment have dominant β-TeO2 along with other polymorphs and amorphous TeO2. From the resistive switching characteristics, it is suggestive that the β-TeO2 phase promotes the conductive filament formation across the highly insulating amorphous matrix. The memory device demonstrates bipolar resistive switching with excellent endurance, retention and on-off ratio. The device also features formation-free switching with low set and reset voltage (0.6 V and -0.8 V respectively) and displays multilevel switching upon varying compliance current. I-V characterization clarifies the conduction path is indeed filamentary type. The result highlights that TeOx can be a prominent resistive switching material for memory and brain-inspired computing devices.

“…TeO 2 glass was prepared by the melt‐quench method. [ 44 ] ITO‐coated glass substrate was sonicated for 30 min in acetone and then in isopropyl alcohol. A KrF laser of wavelength of 248 nm was allowed to incident on the surface of a target with a laser fluence of 3 J cm −2 and the substrate was kept at a distance of 4 cm from the target.…”

Herein, high‐k dielectric behavior of TeO2 thin films is investigated. The films are prepared using pulsed laser deposition on indium tin oxide (ITO)–glass substrates. Increasing the growth temperature has improved the surface roughness, transparency, and bandgap of the films. Films grown at 500 °C display nanocrystalline nature which is reflected in the increase of bandgap to 4.7 eV and is higher than the bulk value of α‐TeO2 (3.7 eV). The nanocrystalline TeO2 films in the metal–insulator–metal configuration show a stable high permittivity of ≈19 with low leakage current (J < 1 × 10−7 A cm−2) and good voltage stability (α = 509 ppm V−2). Field‐effect modulation is observed in the metal–oxide–semiconductor stack configuration with tellurium as a semiconductor. The study suggests nanocrystalline TeO2 as a low‐temperature processable high‐k material with high transparency for transistor applications.

“…e TeO 2 -PbO glass system has been extensively studied. is system has a large glass-forming area, good chemical stability, and thermal properties and is suitable for further research based on this system [7,8]. Adding the transition metal zinc oxide to the glass system can extend the transparent area of the glass in the ultraviolet region.…”

The tellurite 60TeO2-20PbO-(20-x)ZnO-xBaF2 (x = 1, 3, 5, 6, 7, 9, and 11) series glass samples were prepared. The samples’ SEM, XRD, DSC, density, refractive index, and absorption spectra were tested. A self-made optical platform was used to measure and calibrate the refractive index. The relationship between glass composition and crystallinity was discussed. The effects of density, molar refractive index, and metal standard value on the refractive index of glass samples were studied. The results showed that TPZBF glass has a high refractive index, and the refractive index increases with the increase in BaF2 content.
