NEW video on CVD graphene transfer here: ruclips.net/video/aQ0MRfwVSH8/видео.html staff.science.nus.edu.sg/~barbaros/ Ozyilmaz' Group, Graphene Research, National University of Singapore
Hey, have you ever observed monolayer graphene using this method? Dry transfer. I am trying to do this, but I am unable to get thin layers of it
You found the graphene flake in step 3, how did you use that information? Wouldn't you have to look for it again when you go to stamp it onto the hBN flakes, making the first search redundant? I must be missing something
goodddd
Beautiful technique, so well presented
Great video, but how do you get mono or a few layers? That's where I'm struggling.
Did you use PMMA on the Graphene/copper foil before the plasma?
Can you please suggest how can I get Scotch Tape that is suitable for exfoliation purpose?
Where is it possible to purchase the blue tape? Thanks
it's called Nitto tape and it's on amazon
I love that the music is so inspirational
Nice video!very helpful for research who wants to do this. I want to know from where u have buy heating stage and XYZ manipulator??
which tape is that?
@@hanch0321 안녕하세요. 혹시 그 블루 테이프 국내 어디에서 구매할 수 있어요 nitto 밖에 없나요?
Where can buy PDMS film?
@@hanch0321 can you let me know the specific Gel-Pak, I have tried to get information from the company for a month now and they have never responded, thank you
@@user-mn9ob8he7z PF film with retention level X4 and thickness of 6.5 mils
Good video. But how was the stamp peeled off when the two were in contact?
Hi, I have same question, did you find the answer? Thank you
Heat the chip to about 90C and lift the stamp. Stack will be on the stamp
As simple as this video is, it's better than the more complicated videos that don't even show how to do this clear enough🙄
What is that wafer that she is talking about?
Good... but not a big enough.
whats the cost per gram ? How long does it take to make a gram using the scotch method ? Whats the most current most cost effective method of producing a consistent quality of graphine ? thx !
Cool. Now find a way to turn it into a weapon and we'll give you all the money you want
Like what?
Plasma treatment making it hydro phillic I think..
Someone please help: where can I get those graphit flakes and the si wafer?
Lab only or some tech comps
Purpose of plasma treatment is to remove the graphene sheets from the backside of copper foil.
nice
too high...
Bull-plop
Anybody got some clean Si wafer around....I need to find my graphene flake...and do some raman spectroscopy on it....oh wait......I DON"T EVEN HAVE ACCESS TO A LAB!!!
Let me just bust out my optical microscope. -_-
I think the plasma treatment provides an economical solution for the cleaning and activation of component surfaces before further processing-etch.
Looks cool.
Yeah. Look damn near anywhere on the internet.
good mark
Carbon nanotubes are created from rolled graphene. So yes this stuff is pretty freaking strong.
gigaom(dot)com/2013/07/15/what-is-graphene-heres-what-you-need-to-know-about-a-material-that-could-be-the-next-silicon/ Check this out :D
ok...so and then what? is this just theoretical or its fact that this is the strongest material on the planet? any examples that we can see/watch about graphene stuff?
no the microscopes you will have in highschool are around $2,000-$5,000, those ones arent even that good. An optical microscope are around half a million dollars. That's why you will only have them in universities or other research facilities.
i had asked my teacher in school, less than $1000
I think you'd have better luck shaving a little dust off.
That's nanotubes...
A new take on the graveno: graphitebrazil.blogspot.com.br
it's very good i-on trasfer. look it up.
now proved it is strong!
Can someone explain the purpose of the plasma treatment?
just great! It shows how the human can be clever!
I can't see that withholding the weight of an elephant.
michio kaku sent me sort of
we groovin with science
hehe relax. I don't think it meant "101" as in "101 for your home" but "101 for researchers". It did an excellent job at that.
Yes, but how we get a 10 x 10 cm single sheet graphene layer for battery electrodes ???
dammit i havent got a university :(
Science !
