Nov 13, 2020 · Here we show that, in graphene-on-boron-nitride superlattices, Brown-Zak fermions can exhibit mobilities above 10 6 cm 2 V −1 s −1 and the mean free path exceeding …

May 3, 2023 · Here, we report the probe of high-temperature fractal Brown-Zak (BZ) quantum oscillations through magnetotransport in the extreme doping regimes by applying a newly …

These so-called Brown–Zak (BZ) oscillations originate from the repetitive formation of Bloch states at magnetic fields which follow the sequence ϕ/ϕ 0 = 1/q. Upon increasing B, electron …

Jun 29, 2020 · In this paper, we report graphene superlattices of high quality, such as the Brown-Zak fermions exhibit mobilities above 10⁶ cm²/Vs, despite the presence of high magnetic fields, …

Brown-Zak (BZ) oscillations which come in 2 types, 1/B and B periodicity, originating from the generation of integer and fractional MBSs, in the twisted bilayer and trilayer graphene …

Nov 14, 2020 · The authors propose ‘Brown-Zak fermions’ to be the family of quasiparticles existing in superlattices under high magnetic field. This is characterised by a new quantum …

Nov 13, 2020 · Called Brown-Zak fermions these extraordinary particles have the potential to achieve the Holy Grail of 2D materials by having ultra-high frequency transistors which can in …

Nov 13, 2020 · A group of researchers led by Sir Andre Geim and Dr Alexey Berdyugin at The University of Manchester have discovered and characterised a new family of quasiparticles …
