Graphene oxide have high conductivity due to mobility of an electron. It doesn't have any bandgap like metals but have high conductivity for different storage applications etc.. For example i have taken A semiconductor and A has a band gap more than 3 eV. Here my conditions are A semiconductor should not be doped by any other metal or should not be incorporated by any other carbon material but A semiconductor has to increase it's surface area like graphene and it's conductivity also but that A semiconductor material should be useful in many applications like graphene oxide. Is there any method or process or anything else to gain one semiconductor material properties like a graphene surface area and graphene conducting property? Please suggest.
First I would like to say that graphene oxide doesn't show any conductivity, its an insulator. However, graphene is zero bandgap semiconductor. Research is on progress of finding other zero-gap / narrow gap materials and two-dimensional organic conductor α-(BEDT-TTF)2I3 is one example of such a material. Narrow-band III-V or II-VI semiconductor can be obtained by either chemical doping or application of external pressure.
GO is not conductor its insulator due to it contains lots of oxygen containing functionalities. If some one want to make semiconductor graphene here is itself one possibility bases of hydrogenation of graphene or graphene oxide. For hydrogenation of graphene please read the article of D.C. Ellias et al. Science, 2009 and for hydrogenation of GO there are plenty of publications.
Thank you sir for answering but i would like to know the possible ways to make one semiconducting metal oxides like SnO2 into graphene properties for supercapacitor application. I read few papers that they did SnO2 with GO composite for Supercapacitor and Batteries applications...while i am doing on that work i got this doubt so could you please tell me is it possible to make one semiconductor metal oxide like SnO2 properties to graphene properties and SnO2 should not be doped or incorporated by any other. Please
what do you mean by graphene properties?? Surface area or conductivity??
Without doping you can increase only the surface area by making nanodomains, but conductivity like graphene (zero-band gap semiconductor) is difficult withour doping or incorporating.
Sir, Graphene oxide is having Zero-band gap and semi conductor but high conductivity...could you please tell any process to change one semiconductor (SnO2) conducting properties to Graphene conducting properties without doping or incorporating. Please suggest me....
