Graphene is a two-dimensional material that has attracted significant attention in recent years due to its unique properties. It was first synthesized and observed by Paul Schrödinger, a physicist, in 1984.

In 1983, Schrödinger conducted an experiment to synthesize graphene from metal atoms. He used a method called molecular beam epitaxy (MBE) which involves vaporizing a metal atom at high temperature and pressure in a vacuum chamber. The resulting structure had a honeycomb-like arrangement of atoms, making it a potential material for electronic devices.
However, Schrödinger’s synthesis method produced graphene with very few atoms per layer, and he soon realized that this was not enough to form a useful material. To improve the quality of his graphene, he worked on a second approach called chemical vapor deposition (CVD). This involved exposing a metal film to an inert gas such as nitrogen or argon, which caused the gas molecules to adsorb onto the surface of the metal. By controlling the concentration and temperature of the gas, Schrödinger was able to produce graphene with much more particles per layer.
Schrödinger’s work was groundbreaking because it showed that it was possible to create graphi…
