EEE 2056 PHYSICAL ELECTRONICS ASSIGNMENT SAYYEEDA ZAHRA BINTI ABDUL RAHMAN 1102701447 ELECTRONICS GRAPHENE AND IT’S APPLICATIONS

WHAT IS GRAPHENE? Graphene comes from graphite One single layer of graphite is called graphene The atom thick material that is the building unit of all carbon allotropes Has potential for electronics components are made Raise internet speeds and prolong the lives of the computer

STRUCTURE OF GRAPHENE Includes the band modulations Considered semimetal The mass material is different in the terms of manipulation of band gap in nanostructures Graphene nanomesh is the latesh graphene nanostructure Successfully implemented in gas molecule sensor, field effect transistor and others

PROPERTIES OF GRAPHENE Has band gap zero High electron mobility Individual electrons moves on the surface is massless The strongest material in weight Strong chemical bonds High transparency High thermal conductivity

APPLICATIONS OF GRAPHENE Good applications in electronic packaging Long lasting result for touch screen devices Graphene devices on radio frequency Several types of sensor - Monoxide sensor - Infrared sensor Terahertz polarizer Planar absorber Faraday rotation

DANGERS OF GRAPHENE Potential in toxicity Have mobility in water Effects on red blood cells Significant exposure risk through inhalation The jagged edge of graphene particles

SUMMARY The usage of graphene have its own pros and cons Graphene has a very big potential in the industries Able to improve computing performance Highly unique and not usually found in other materials Graphene is soon to be practical Risky but still in experiment stages
