Near-field photocurrent nanoscopy on bare and encapsulated graphene
Achim Woessner, Pablo Alonso-González, Mark B. Lundeberg +14
Opto-electronic devices utilizing graphene have already demonstrated unique capabilities, which are much more difficult to realize with conventional technologies. However, the requ…
High-Responsivity Graphene-Boron Nitride Photodetector and Autocorrelator in a Silicon Photonic Integrated Circuit
Ren-Jye Shiue, Yuanda Gao, Yifei Wang +7
Graphene and other two-dimensional (2D) materials have emerged as promising materials for broadband and ultrafast photodetection and optical modulation. These optoelectronic capabi…
Fractional fractal quantum Hall effect in graphene superlattices
Lei Wang, Yuanda Gao, Bo Wen +6
The Hofstadter energy spectrum provides a uniquely tunable system to study emergent topological order in the regime of strong interactions. Previous experiments, however, have been…
