Hi there Mr. Phước Văn Trương ,

I recommend you using spin coating methods with the Sol-Gel precursors of TiSe2 combined with a polymer binder, then calcinate it in an oven to ensure your desired structure.

we used the exact same method for synthesising TiO2 nano needles from titanium alkoxide and it worked wonderfully.

I have made TiSe2 from solution using sol-gel precursors such as titanium tetraisopropoxide, but instead of reacting with water I used hydrogen selenide (H2Se). It is highly toxic and water must be kept out because it is more reactive than H2Se. I am not sure this could be adapted for thin film growth however.

PLD offers good control over film composition and crystallinity, especially when a TiSe₂ target is used. It may not be more economical than CVD, but it can be a more convenient alternative in research settings (more flexible and faster to set up for producing a small number of high-quality samples).

thanks to honorable work of Mr. Jawher Makhlouf for this consice answer directly copied from AI.

this precise answer should be rewarded to something not less than a noble prize.

thanks for your time and effort

Mr Soroush Asgharian You had time for sarcasm and you don't for research on your topic? That reflects the quality of the researcher. By the way, this isn't from an AI, Mr. Idiot. Literally, I was wrong to answer you.

Best of luck.

Thanks for the compliment, Mr. Jawher Makhlouf; I love being called Detective Conan.

For the record, and since you deleted your previous answer, I would like to share it here so others are also aware of these kinds of personalities and how to deal with them in the future.

Thanks for your AI-assisted time and effort.

Soroush Asgharian go and do research to have new paper and acheivement, plenty of ducks here just doing noise

for your infos: i don't delated it, you're masqued, i will never delete a source of information for serious people

but for you as noiser: it's yes

AI significantly facilitates research by automating tasks, enhancing data analysis, and improving access to information. AI-powered tools can process large datasets, identify patterns, and offer insights that might be missed by human researchers, while also streamlining literature reviews and improving the accuracy of research findings.

does we use technology or do like Soroush Asgharian just noise and wasting time

Yes, there are several alternative methods for fabricating TiSe₂ thin films that can be simpler, more economical, and more accessible than traditional chemical vapor deposition (CVD), while still aiming for high structural quality. CVD is a powerful technique, but it can be complex and expensive due to the need for specific volatile precursors and controlled environments.

One promising alternative is a two-step process that combines physical vapor deposition (PVD) with selenization. This method is considered more scalable and straightforward:

This two-step approach offers several advantages:

• Scalability: The sputtering step allows for the deposition of titanium films over large areas, which is beneficial for large-scale production.
• Accessibility: Magnetron sputtering is a more common and generally less complex technique to set up than many advanced CVD systems.
• Controllability: By adjusting parameters in both steps (e.g., sputtering power, deposition time, selenization temperature, and time), researchers can influence the resulting film's morphology, thickness, and crystal structure.

While this method can produce films with good structural quality, it's important to note that controlling parameters is crucial to prevent issues like granular textures or voids.

Other methods also exist, though they may have different trade-offs in terms of complexity and cost:

• Molecular Beam Epitaxy (MBE): While known for producing films of the highest quality with precise control over thickness and composition, MBE is typically an extremely slow and costly process, making it less accessible and economical for large-scale applications.
• Liquid-Phase Exfoliation: This method involves breaking down bulk TiSe₂ crystals into individual 2D sheets in a liquid solvent. It's a "bottom-up" approach that can produce high-quality, single- or few-layer sheets, but fabricating continuous, large-area thin films can be challenging.
• Sol-Gel Method: This is a low-temperature, low-cost solution-based process. While widely used for fabricating oxide films, its application for TiSe₂ can be more complex, requiring careful selection of precursors and precise control over the process to achieve the desired stoichiometry and structural quality.

In summary, the two-step process involving magnetron sputtering followed by selenization presents a promising balance between simplicity, cost-effectiveness, and the ability to produce high-quality TiSe₂ thin films for a variety of applications.

Thank you again for your new AI-generated answer, habibi....

Judging by the timing of the messages and the changes you made to correct what was wrong in the first place, you seem like a much less dumb person now.

Congratulations on your new achievement, and good luck!
