Anomalous twin boundaries in 2D materials
A. P. Rooney, Z. Li, W. Zhao +7
The high mechanical strength and excellent flexibility of 2D materials such as graphene are some of their most important properties [1]. Good flexibility is key for exploiting 2D m…
Excess resistivity in graphene superlattices caused by umklapp electron-electron scattering
J. R. Wallbank, R. Krishna Kumar, M. Holwill +11
Umklapp processes play a fundamental role as the only intrinsic mechanism that allows electrons to transfer momentum to the crystal lattice and, therefore, provide a finite electri…
High-order fractal states in graphene superlattices
R. Krishna Kumar, A. Mishchenko, X. Chen +7
Graphene superlattices were shown to exhibit high-temperature quantum oscillations due to periodic emergence of delocalized Bloch states in high magnetic fields such that unit frac…
High-temperature quantum oscillations caused by recurring Bloch states in graphene superlattices
R. Krishna Kumar, X. Chen, G. H. Auton +13
Cyclotron motion of charge carriers in metals and semiconductors leads to Landau quantization and magneto-oscillatory behavior in their properties. Cryogenic temperatures are usual…
