GRAPHENE AND IT’S APPLICATIONS

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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
