State Grid Microfilm Tao

How is TAO X thin film deposited on Pt/Ti/Sio 2/si substrates?

A TaO x thin film of approximately 30 nm thick was deposited on Pt/Ti/SiO 2 /Si substrates by reactive rf-sputtering technique at room temperature. During the TaO x thin film deposition, the rf-sputtering power and the deposition pressure were maintained at 100 W and 2 mTorr, respectively.

Does TAO X thin film have Rs?

In this work, the highly promising RS performance of the TaO x thin film is demonstrated and microscopic analyses by high-resolution transmission electron microscope (HR-TEM) provide direct observation on the origin of the RS in the TaO x thin film. Figure 1 (a) shows I–V hysteresis characteristic of a Ta/TaO x /Pt capacitor-like device.

How to measure electrical properties of TAO X thin film?

A top electrode of 30 nm thick Ta layer was deposited on the TaO x film by dc-sputtering method at room temperature and patterned through photolithography and lift-off process, in order to measure the electrical properties of the TaO x thin film.

Does TAO X thin film have a high endurance characteristic?

Yang. et al. reported the highly promising endurance characteristic over ~10 10 RS cycles of the TaO x thin film, which is attributed to simple thermodynamic equilibrium phases of Ta-O system in the range of conventional RS operation condition 7.

What reveals the origin of electric conduction paths in TaOx thin film?

The observed Ta metal clusters unveiled the origin of the electric conduction paths in the TaOx thin film at the LRS.

How reliable is a TAO X memristor?

The TaO x memristor had MVC states where oxygen vacancies migrated to create a Ta-rich local regions to be responsible for the stable switching behavior. The MVC cycling reliability was greater than 50 000 times, with a two-state endurance of at least 10 12 cycles.
