With the rapid development of topological states in crystals,the study of topological states has been extended to quasic......

Graphene devices on standard SiO/Si substrates are facing a bottleneck.These kind of devices can only show the primary c......

We show graphene discerns an unconventional sequence of quantized Hall conductivity, when subject to both magnetic field......

　　We report high-quality graphene p-n-p junctions achieved by controlled metallic diffusion.Generally,metal deposition......
