MIT Physicists Discover Fractional Electron Charges in Graphene
A groundbreaking study reveals that electrons can exhibit fractional charges in a five-layer graphene structure without the need for an external magnetic field.
- Physicists at MIT have observed the fractional quantum Hall effect in graphene, a material previously not expected to exhibit such behavior.
- The discovery was made in a five-layer graphene structure, where electrons behave as if they are broken into fractional charges.
- This effect occurs without the need for any external magnetic field, marking the first evidence of the 'fractional quantum anomalous Hall effect' in graphene.
- The findings could have significant implications for quantum computing, offering a simpler system for realizing exotic electronic states.
- The research team is exploring multilayer graphene for other rare electronic states, indicating potential for further groundbreaking discoveries.
