Moiré Periodic and Quasiperiodic Crystals in Heterostructures of Twisted Bilayer Graphene and Hexagonal Boron Nitride
Xinyuan Lai, Guohong Li, Angela M. Coe +4
Stacking two atomic crystals with a twist between their crystal axes produces moiré potentials that modify the electronic properties. Here we show that double moiré potentials gene…
Cryogen-free modular scanning tunneling microscope operating at 4-K in high magnetic field on a compact ultra-high vacuum platform
Angela M. Coe, Guohong Li, Eva Y. Andrei
One of the daunting challenges in modern low temperature scanning tunneling microscopy (STM) is the difficulty of combining atomic resolution with cryogen free cooling. Further fun…
Quick connect scanning tunneling microscope head with nested piezoelectric coarse walkers
Angela M. Coe, Guohong Li, Eva Y. Andrei
To meet changing research demands, new scanning tunneling microscope (STM) features must constantly evolve. We describe the design, development, and performance of a modular plugin…
