What is the significance of the 'magic angle' in graphene?

• It allows graphene to change color.

• It enables graphene to become either an insulator or a superconductor.

• It increases the strength of graphene.

• It makes graphene magnetic.

What is the main challenge with using a scanning tunneling microscope to study 'magic angle' graphene?

• It damages the graphene layers.

• It is too slow for large-scale mapping.

• It requires extremely low temperatures.

• It cannot detect the twist angle.

What does SQUID stand for in the context of graphene research?

• Superconducting Quantum Interference Device

• Super Quick Interference Detector

• Super Quantum Interference Detector

• Superconducting Quantum Information Device

How does the four-layer 'magic angle' structure differ from the two-layer structure?

• It is less stable.

• It can be tuned using an electric field.

• It is only an insulator.

• It does not exhibit superconductivity.

What potential future application is mentioned for twistronics?

• Creating flexible screens.

• Developing high-temperature superconductors.

• Building stronger materials.

• Enhancing solar panel efficiency.
