Graphene is a two-dimensional material consisting of carbon atoms arranged in a hexagonal lattice, known for its unique properties, including high strength and electrical conductivity. However, despite its incredible potential, graphene has not yet been widely studied or manufactured due to its low density and sensitivity to environmental factors.

One promising application of graphene is in the field of electronics. Its strong conductive properties make it an ideal material for use in electronic devices such as transistors and batteries. Graphene also exhibits excellent mechanical stability and can withstand exposure to extreme temperatures, making it suitable for use in various industrial applications.
To demonstrate the existence of graphene on SiO2 using optical microscopy, researchers have developed a new technique that uses infrared spectroscopy (IR) to detect the presence of graphene. IR spectroscopy allows for the detection of minute changes in the energy levels of molecules, which can reveal the presence of specific compounds or materials.
In this study, researchers used a SiO2 substrate with a graphene layer attached to it to demonstrate the presence of graphene on the surface. The graphene layer was grown on top of a SiO2 substrate by means of chemical vapor deposition (CVD), a process in which gases are vaporized and deposited onto a surface to form a layer of material.
The IR spectroscopy experiment revealed that the graphene layer on the SiO2 substrate was significantly different from the SiO2 substrate without the graphene layer. This indicates that graphene has been incorporated into the surface of the SiO2 substrate, forming a new material with unique properties.
This discovery provides important insights into the possibility of using graphene as a functional material in electronic devices. By developing methods to grow graphene on a variety of substrates, researchers hope to overcome the limitations of current techniques and enable the widespread adoption of graphene as a material for use in electronic devices.

Overall, the study of graphene on SiO2 using optical microscopy demonstrates the potential of this material to revolutionize the field of electronics. With continued research and development, it is likely that graphene will become a ubiquitous material in our daily lives, enabling us to create more efficient and sustainable technologies.
