Lesson 1, Topic 1
In Progress
Atom Arrangement (Carbon) vs Material Property
- good electrical conductor, lubricant
Graphite in 2D sheet


- Diamond-hardest material, electrical insulator, thermal conductor
3D-Diamond


- Good conductivity, high tensile strength
- Similarity: contain only one kind of atom -carbon.
- Difference: how those atoms are arranged.
- Crystal structure –related to intrinsic electrical properties of material.
