Large effective mass and interaction-enhanced Zeeman splitting of -valley electrons in MoSe
Stefano Larentis, Hema C. P. Movva, Babak Fallahazad +6
We study the magnetotransport of high-mobility electrons in monolayer and bilayer MoSe, which show Shubnikov-de Haas (SdH) oscillations and quantum Hall states in high magnetic…
Tunable Valley Populations in Hole-Doped Trilayer WSe
Hema C. P. Movva, Timothy Lovorn, Babak Fallahazad +7
We present a combined experimental and theoretical study of valley populations in the valence bands of trilayer WSe. Shubnikovde Haas oscillations show that trilayer holes p…
Coherent Interlayer Tunneling and Negative Differential Resistance with High Current Density in Double Bilayer Graphene-WSe2 Heterostructures
G. William Burg, Nitin Prasad, Babak Fallahazad +8
We demonstrate gate-tunable resonant tunneling and negative differential resistance between two rotationally aligned bilayer graphene sheets separated by bilayer WSe2. We observe l…
Tunable Moiré Bands and Strong Correlations in Small-Twist-Angle Bilayer Graphene
Kyounghwan Kim, Ashley DaSilva, Shengqiang Huang +7
According to electronic structure theory, bilayer graphene is expected to have anomalous electronic properties when it has long-period moiré patterns produced by small misalignment…
Density-Dependent Quantum Hall States and Zeeman Splitting in Monolayer and Bilayer WSe
Hema C. P. Movva, Babak Fallahazad, Kyounghwan Kim +5
We report a study of the quantum Hall states (QHSs) sequence of holes in mono- and bilayer WSe. The QHSs sequence transitions between predominantly even and predominantly odd f…
Shubnikov-de Haas oscillations of high mobility holes in monolayer and bilayer WSe: Landau level degeneracy, effective mass, and negative compressibility
Babak Fallahazad, Hema C. P. Movva, Kyounghwan Kim +5
We study the magnetotransport properties of high mobility holes in monolayer and bilayer WSe, which display well defined Shubnikov-de Haas (SdH) oscillations, and quantum Hall…
