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…
High-Performance Atomically-Thin Room-Temperature NO2 Sensor
Amin Azizi, Mehmet Dogan, Hu Long +7
The development of room-temperature sensing devices for detecting small concentrations of molecular species is imperative for a wide range of low-power sensor applications. We demo…
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…
Wafer Scale Homogeneous Bilayer Graphene Films by Chemical Vapor Deposition
Seunghyun Lee, Kyunghoon Lee, Zhaohui Zhong
The discovery of electric field induced bandgap opening in bilayer graphene opens new door for making semiconducting graphene without aggressive size scaling or using expensive sub…
