Nature of novel moiré exciton states in WSe/WS heterobilayers

Mit H. Naik, Emma C. Regan, Zuocheng Zhang +18

Moiré patterns of transition metal dichalcogenide (TMD) heterobilayers have proven to be an ideal platform to host unusual correlated electronic phases, emerging magnetism, and cor…

Efficient Fizeau Drag from Dirac electrons in monolayer graphene

Wenyu Zhao, Sihan Zhao, Hongyuan Li +11

Fizeau demonstrated in 1850 that the speed of light can be modified when it is propagating in moving media. Can we achieve such control of the light speed efficiently with a fast-m…

Correlation-Driven Electron-Hole Asymmetry in Graphene Field Effect Devices

Nicholas Dale, Ryo Mori, M. Iqbal Bakti Utama +13

Electron-hole asymmetry is a fundamental property in solids that can determine the nature of quantum phase transitions and the regime of operation for devices. The observation of e…

Ultra-high-resolution imaging of moiré lattices and superstructures using scanning microwave impedance microscopy under ambient conditions

Kyunghoon Lee, M. Iqbal Bakti Utama, Salman Kahn +13

Two-dimensional heterostructures with layers of slightly different lattice vectors exhibit a new periodic structure known as moire lattices. Moire lattice formation provides a powe…

Visualization of the flat electronic band in twisted bilayer graphene near the magic angle twist

M. Iqbal Bakti Utama, Roland J. Koch, Kyunghoon Lee +15

Bilayer graphene was theorized to host a moire miniband with flat dispersion if the layers are stacked at specific twist angles known as the magic angles. Recently, such twisted bi…
