Graphene Synthesis Using Indigenous Low-pressure Chemical Vapour Deposition Device

Single Layer Graphene: Graphene is a single layer of graphite. The remarkable thing about it is that its crystalline structure is two-dimensional. Graphene is strong and stiff amazingly thin, almost completely, transparent extremely light and an excellent conductor of electricity and heat.

However, synthesis this is of graphene is a tedious process, but now scientists at CSIR-National physical laboratory in New Delhi have successfully synthesis Graphene, which can be used in next-generation Quantum devices, like high-speed computers and memory devices.

Graphene is an alloy of carbon. It is the form of a two-dimensional atomic-scale hexagonal lattices in which one atom form each vertex. Vertex is the basic structural element of other allotropes, including graphite and charcoal.

Graphene Synthesis

Graphene has become a versatile material as it is the lightest and strongest material along with an ability to conduct heat & electricity better than any other. Earlier, it was believed that the synthesis of graphene is not possible.

However, isolation of graphene by dissecting it from a piece of graphite made the picture clear and instigated scientist. So focus on the synthesis of graphene sheets.

Therefore many researchers have tried to synthesize graphene, but very few of them succeeded because the manufacturing and maintenance cost was too high.

This challenge was very well taken up by a team of researchers led by DR. Bipin Kumar Gupta from the Advanced Materials and devices Metrology division at CSIR-National physical laboratory in New Delhi.

They have successfully synthesized metal grate graphene by using indigenously design technique in India, which is much durable and cost-efficient too.

Low-pressure Chemical Vapour

Many techniques have been used so far to produce graphene at a large scale. However, amongst these methods, chemical vapour deposition method has been found to be the most promising method used to produce graphene at a large scale.

But the instrumentation and maintenance cost used to be very high. This instigated Doctor Bipin Kumar and his team to focus on synthesizing graphene using low-cost technology.

The team focused on a method of low-pressure chemical vapour deposition where they modified the system and came up with high-quality graphene synthesized on thin copper paint. The method was found to be reproducible as it has shown its efficiency up to 30 times.

The device developed by the team is very effective and it costs about one-tenth as compared to important instruments.


The synthesized high-quality graphene can easily be transferred to any surface and use in next-generation devices such as bioelectronic sensory devices for monitoring various biomedical parameters from serum to modify the LCDs, touch screens and it can be extended up to portable and flexible electronic devices.

This innovation by Dr Bipin Kumar Gupta and his team is commendable and has huge potential in the field of graphene synthesis using indigenous low-pressure chemical vapour deposition device. The technique will be more useful in all possible sectors, especially in electronics.
