Scalable van der Waals epitaxy of tunable moiré heterostructures
Matthieu Fortin-Deschênes, Kenji Watanabe, Takashi Taniguchi +1
The unique physics found in moiré superlattices of twisted or lattice-mismatched atomic layers hold great promise for future quantum technologies. However, twisted configurations a…
Photothermal Engineering of Graphene Plasmons
Renwen Yu, Qiushi Guo, Fengnian Xia +1
Nanoscale photothermal sources find important applications in theranostics, imaging, and catalysis. In this context, graphene offers a unique suite of optical, electrical, and ther…
Protective Molecular Passivation of Black Phosphorous
Vlada Artel, Qiushi Guo, Hagai Cohen +4
Black phosphorous (BP) is one of the most interesting layered materials, bearing promising potential for emerging electronic and optoelectronic device technologies. The crystalline…
Black Phosphorus Mid-Infrared Photodetectors with High Gain
Qiushi Guo, Andreas Pospischil, Maruf Bhuiyan +11
Recently, black phosphorus (BP) has joined the two dimensional material family as a promising candidate for photonic applications, due to its moderate bandgap, high carrier mobilit…
Anisotropic Black Phosphorus Synaptic Device for Neuromorphic Applications
He Tian, Qiushi Guo, Yunjun Xie +5
Synapses are functional links between neurons, through which "information" flows in the neural network. These connections vary significantly in strength, typically resulting from t…
Synthesis of thin-film black phosphorus on a flexible substrate
Xuesong Li, Bingchen Deng, Xiaomu Wang +8
We report a scalable approach to synthesize a large-area (up to 4 mm) thin black phosphorus (BP) film on a flexible substrate. We first deposited a red phosphorus (RP) thin-film on…
