This went against all accepted knowledge in the silicon community: It is widely believed at the time among practitioners of the silicon art that the oxide layer used to mask dopants was dirty and, as a result, had to be etched away.

Further, I think that graphene, a 2-dim layer of hexagonal carbon. with different P and N dopants will also become a solar cell of the future.

The impurities – or dopants – are added to semiconductors to fine-tune their electronic properties.

Correctly doping the ultra-thin channels that the consortium hopes to use is simply too difficult-hence the decision to do without dopants altogether and build channels out of pure silicon.

As transistors get smaller, however, laying down n-type and p-type materials in proximity gets harder, thanks once again to fluctuations in the concentrations of dopants.

In graphene, on the other hand, dopants are generally deposited on top of the carbon sheet rather than taking the place of some of the carbon atoms.
