AI Article Synopsis
- Twisted graphene, particularly at the magic angle, has gained interest due to its unique properties but faces instability issues that hinder practical applications.
- The twist angles between layers can change spontaneously, with heat and strain speeding up this process.
- A theoretical solution involves using organic linkers to 'pillar' the twisted graphene, which has been supported by numerical calculations demonstrating its necessity and feasibility.
Article Abstract
Twisted graphene, including magic angle graphene, has attracted extensive attentions for its novel properties recently. However, twisted graphene is intrinsically unstable and this will obstruct their application in practice, especially for twisted nano graphene. The twist angles between adjacent layers will change spontaneously. This relaxation process will be accelerated under heat and strain. To solve this problem, we propose a strategy of pillaring twisted graphene by organic linkers in theory. The necessity and feasibility of this strategy is proved by numerical calculation.
