Giant Frictional Drag in Double Bilayer Graphene Heterostructures
Kayoung Lee, Jiamin Xue, David C. Dillen +3
We study the frictional drag between carriers in two bilayer graphene flakes separated by a 2 5 nm thick hexagonal boron nitride dielectric. At temperatures () lower than $\…
Gate-Tunable Resonant Tunneling in Double Bilayer Graphene Heterostructures
Babak Fallahazad, Kayoung Lee, Sangwoo Kang +10
We demonstrate gate-tunable resonant tunneling and negative differential resistance in the interlayer current-voltage characteristics of rotationally aligned double bilayer graphen…
Chemical Potential and Quantum Hall Ferromagnetism in Bilayer Graphene
Kayoung Lee, Babak Fallahazad, Jiamin Xue +5
Bilayer graphene has a unique electronic structure influenced by a complex interplay between various degrees of freedom. We probe its chemical potential using double bilayer graphe…
Quantum Hall Effect in Bernal Stacked and Twisted Bilayer Graphene Grown on Cu by Chemical Vapor Deposition
Babak Fallahazad, Yufeng Hao, Kayoung Lee +3
We examine the quantum Hall effect in bilayer graphene grown on Cu substrates by chemical vapor deposition. Spatially resolved Raman spectroscopy suggests a mixture of Bernal (A-B)…
Magnetotransport Properties of Quasi-Free Standing Epitaxial Graphene Bilayer on SiC: Evidence for Bernal Stacking
Kayoung Lee, Seyoung Kim, M. S. Points +3
We investigate the magnetotransport properties of quasi-free standing epitaxial graphene bilayer on SiC, grown by atmospheric pressure graphitization in Ar, followed by H inter…
Spin-Polarized to Valley-Polarized Transition in Graphene Bilayers at in High Magnetic Fields
Seyoung Kim, Kayoung Lee, Emanuel Tutuc
We investigate the transverse electric field () dependence of the =0 quantum Hall state (QHS) in dual-gated graphene bilayers in high magnetic fields. The longitudinal resist…
