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.
What else can I help you with?
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 material improved transistors?
The introduction of silicon as a semiconductor material significantly improved transistors, especially with the development of silicon-based integrated circuits. Silicon's favorable electronic properties, abundance, and ease of doping with impurities allowed for greater control over electrical conductivity. This advancement led to the miniaturization of electronic components and the proliferation of modern electronics. Additionally, materials like gallium arsenide and more recently, graphene and other 2D materials, have further enhanced transistor performance in specific applications.
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.
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.
How does the conductivity of graphene compare to that of silver?
Graphene has higher conductivity than silver.
What is a true statement about the metalloid silicon?
silicon is a better conductor of electric current than sulfur is.
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 has a higher operating temperature and better thermal stability compared to germanium, making it more reliable for electronic devices. Additionally, silicon's oxide layer forms a better insulating material for integrated circuits, enhancing its performance. Silicon also has a wider bandgap than germanium, allowing for better control of electrical conduction.
How can graphene be produced efficiently and effectively?
Graphene can be produced efficiently and effectively through methods such as chemical vapor deposition, liquid-phase exfoliation, and epitaxial growth on silicon carbide. These techniques allow for the large-scale production of high-quality graphene with minimal defects. Additionally, advancements in research and technology continue to improve the production processes for graphene, making it more accessible for various applications.
How are DNA microchips better than silicon microchips?
Theoretically DNA based processors have the potential to be much faster than current silicon tecnology.
What is the hardness of graphene on the mohs scale?
graphene according to how much it can hold (calculator) and how dense it is.
Is a silicon better conductor of an electric current than sulfur?
Yes, silicon is a better conductor of electric current than sulfur. Silicon is a semiconductor that can conduct electricity under certain conditions, while sulfur is an insulator that does not conduct electricity well.
How can one obtain graphene and what are the methods for acquiring this material?
Graphene can be obtained through various methods, including mechanical exfoliation, chemical vapor deposition, and epitaxial growth on silicon carbide. These methods involve processes such as separating layers of graphite, depositing carbon atoms on a substrate, or growing graphene on a specific material. Each method has its own advantages and limitations in terms of scalability, cost, and quality of the graphene produced.
Is silicon a better conductor of electric current than silver is?
No, silicon is not a better conductor of electricity than silver. Silver is one of the best conductors of electricity due to its high electrical conductivity, surpassed only by materials like copper and gold. Silicon is a semiconductor and has lower conductivity compared to silver.
Why silicon is the more semiconductor than germanium?
Silicon is a more popular semiconductor than germanium due to factors such as its wider band gap, higher thermal stability, and better abundance in nature. Silicon also has better manufacturing processes and can operate at higher temperatures, making it more suitable for a wide range of electronic applications.
