What will be the modified work function of indium tin oxide (ITO) when exposed to UV-ozone?

Is there any dependence on the exposure time? If yes, how can it be tuned? UV-ozone treatment makes the ITO surface smooth and avoids any shorts between the various layers while fabricating...

What is the simplest method to get graphene in bulk quantities?

Unzipping MWNTs is easy, but the filtration process (conc. H2SO4) using a micron filter is difficult. I have tried this method and successfully prepared graphene. Due to this reason, only very...

Sreekanth J Varma

Thanks George..plz give more details on obtaining high mobilities in doped graphenes...Thank you again for the references...

Pramoda K. Nayak

The best way to prepare doped graphene is by the use of Boron source and Nitrogen source in chemical vapor deposition (CVD).

D. W. Boukhvalov

Other way of the graphene doping is decoration it by metal or alkali adatoms (there was a several works) or by molecular doping.

Subrata Ghosh

I'm agree with Promoda Nayak , because it is controllable.

Thank you...I got a few references related to molecular doping...will come back after reading the papers...
