It is hard to answer to that question. Both materials have advantages and disadvantages. Silicon is semiconductor so you can turn it on and off and you can make numerous field effect transistors or effective solar cells. However, graphene is zero-band-gap semiconductor which is very conductive. It is not conventional semiconductor. People are still trying to introduce a band gap to graphene to yield true semiconducting graphene.
Both materials are legends in the field. Each has advantage. Most likely Silicon will continue to dominate the conventional semiconductor industry and solar cells. However graphene (and graphene derivatives) will be integral part of high frequency devices, diodes, sensors, and some solar cells.

Why silicon is better semiconductor material than GAAs?
Because comparing with ga,as silicon have more attraction force with their outer most electons . The si atomic number is less than all above
Name three of the best conductive materials.?
Leaving aside superconductors: graphene, silver, copper.
What is the effect of silicon in carbon steel?
Silicon is used as a deoxidising (killing) agent in the melting of steel, as a result, most steels contain a small percentage of silicon. Silicon contributes to hardening of the ferritic phase in steels and for this reason silicon killed steels are somewhat harder and stiffer than aluminium killed steels.
What allowed computer technology to develop?
THE SILICON CHIP -The term silicon is important in the computer industry. Microchips that let computers work are made from silicon. Scientists developed the first trial silicon chip in 1958. Before that time computers were made of transistors. In 1958 scientists thought that silicon microchips were impressive because each chip could hold more than 30 transistors. Today's silicon chips often have more than a million transistors. Silicon microchips have helped make modern computer technology possible.
What is the most familiar semiconductor?
silicon and germanium
Will graphene chips replace silicon chips in computer?
Silicon transistors are approaching the point where further miniaturization will no longer be possible. It is expected that once silicon transistors reach 16nm size, optical lithography will no longer be capable of making smaller images. Thus, unless all progress in transistor size is terminated and performance improvements are limited to processor architecture alone, it is very likely that chip manufacturers will move to graphene as a way to get smaller transistors. However, graphene has flaws. One example is that graphene transistors are very "leaky" compared to those made of silicon- that is, more charge can escape from them. This means that graphene chips are likely to run much hotter than silicon chips.
Why germanium is better than silicon?
products made by silicon are more stable than those made by germanium
Is graphene technology can replace the present silicon technology in future?
Perhaps. Maybe diamond film wafer or nanotube will get there first.
Why is silicon a better semiconductor than germanium?
Silicon is a good semi conductor than germanium because silicon is more readily available, cheaper and stable.
What is a true statement about the metalloid silicon?
silicon is a better conductor of electric current than sulfur is.
What is the hardness of graphene on the mohs scale?
graphene according to how much it can hold (calculator) and how dense it is.
How are DNA microchips better than silicon microchips?
Theoretically DNA based processors have the potential to be much faster than current silicon tecnology.
Is a silicon better conductor of an electric current than sulfur?
yes
What is the density of graphene and carbyne?
Graphene aerogel - 0,16 mg/cm3 (7,5 less than air) Carbyne - 3430 mg/cm3
What is a graphene filter?
Graphene is a sheet of Carbon atoms, or one layer of Graphite ("lead" in a pencil). A graphene filter is a filter made of graphene.
Why silicon is better semiconductor material than GAAs?
Because comparing with ga,as silicon have more attraction force with their outer most electons . The si atomic number is less than all above
What are the properties of graphene?
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
