Now it? will need a Graphene Valley! Instead of Silicon
Benzene is C6H6 ...
Benzene is C6H6 which makes it a hydrocarbon...not just carbon, graphene is? just a hexagon of carbon surrounded by hexagons of carbon

Nice, a? WiTec alpha 300, my favorite machine!
First of all, ...
First of all, congratulations, it's a great video.
If fact everything is very clear.
As far as I know in Raman spectroscopy, you can use 785 nm (red laser) and 532 nm (green laser, the one you guys use).?
Have you tried the 785 nm laser with the graphene? If so on which bands does the bands appear.
Also have you tried to have a spectra of the graphene, in Medium Infrarred, Near Infrarred or Far Infrarred?
Thanks in advance for your answer.

@ianhallam because you're? an amateur scientist that wont get any respect without proper goggles!
It's worth to see ...
It's worth to see electrochromism in? graphene:

very well?

Nice, straightforward explanation with a little bit of? ra-ra for science. I had heard of the "Scotch tape technique" but now I know how its done.
