Chemical Vapour Deposition (CVD)

[@saleemun8842]

Thank you so much for this outstanding explanation. This is so helpful and gives us a lot of better understanding about the technologies of nano-structure and especially a better imagination when I am reading an academic paper. I am very grateful, much appreciation of your work.

[@zahidurrahaman428]

Thank you for this very helpful video. A good starting guide for beginners.

[@jimburnsjr.]

Super cool stuff, thank you for upgrading our minds; and our world.

Love pyrolysis. Very good quality, and can be done in atmospheric pressure. Only problem you need proper chemical precursors. That is why I moved to a modified sputtering arrangement, took me two years to perfect its quality, but I did it! I have perfectly transparent and conducting TCOs, among any other thin film I want.

[@Slava870909]

Show in the video what coatings you apply?.

[@BillDemos]

@@Slava870909 I do all coatings. I started with Zinc Oxide doped with Aluminium (ZnO:Al).

[@enzov9772]

What level/standard cleanroom is this process performed in?

[@matchem9178]

Very useful, thanks. But, what about the safety glasses?

[@vighneshraj5694]

Very interesting. Thank you for the demo.

How can I deposit silver on a ceramic pallet? Thanks N Das

Hello, what size are the nanoparticles of molten gold emitted when evaporating due to high temperature?

[@naveenbommanahalli6290]

A very Interesting video about CVD process with good explanation , Thank you! If possible, please make a video on PVD Coating processes as well ( Thermal Evaporation & Sputtering methods specially )

[@divyangpatel1709]

Thank you so much Sir. It’s a very helpful video to understand CVD process

[@rez17]

Fantastic presentation! Enjoyed it a lot. I have one question though: Is the silicon wafer boat maintained at the same temperature throughout its length, realistically speaking? If not, then should we expect a gradual decrease in BN concentration through the length of silicon wafer also? (Following similar logic to the gradual change in concentration in the precursor tube*) Or will the thermal diffusion of gas at that temperature nullify such effects?

[@EugeneMineev-o3g]

The second guess is the right one. The thermal diffusion is one of the top advantages of CVD processes because of uniform layer growth

[@MRwanis88]

What is the model of the used device?

[@Szapez]

If the material that is being used as a coating is inside the chamber with the substrate isn't it qualified as a PVD method?

[@LearnToLive-zs8mz]

the video is very intuitive

[@sachinkumarsharma9785]

We used the cvd process in diamond manufacturing

[@PaulGaurav]

Great Stuff! would love to have more such videos!!

[@lisandromilesi794]

Excellent! I have a question, why do the "B-N" nanoparticles deposit? I mean, I know they are not vollatile as H2O and H2 (byproducts) but I imagine that they're so light that the gas flow should carry them away also.

[@executorarktanis2323]

Good question

[@SentinelAerospaceOfficial]

They did leave it for 10 hours so i guess over time, all of it formed on the substrate at some point

[@ismailgunduz7146]

Thank you so much for helping me. I would like to ask you something, is it possible to obtain fiber structure by chemical vapor deposition (cvd) method?

[@pengwu2581]

Yes, by using some gas precursors and catalyst, you can have some nano fibers like carbon nanotubes grown by CVD process. U can take a look at some review papers about CNT.

[@theDucklings9908]

Lol it was cool to watch but I don't think such setup can be found in my place, . Hope an eejit comments to this. Thanks sir.

[@userGGG702]

Thank you for sharing sir.

Probably a stupid question for experts like you. Can you tell me what is the current infinitesimal? The smallest object? what is the smallest thing that we can see through microscopy/microscope/s? Are you seeing the smallest things? And also what do you use as a sample? Can anything be used as a sample? Cheers, from a new subscriber.

[@suriyaprakash8663]

We can see atoms, their structures through microscope, obviously not our normal microscopes but SEM and TEM type microscope, where mapping is done by electrons
