Black Phosphorus Mid-Infrared Photodetectors with High Gain
Qiushi Guo,Andreas Pospischil,Maruf A. Bhuiyan,Hao Jiang,He Tian,Damon B. Farmer,Bingchen Deng,Cheng Li,Shu-Jen Han,Han Wang,Qiangfei Xia,Tso-Ping Ma,Thomas Mueller,Fengnian Xia +13 more
TL;DR: Noise measurements show that such BP photodetectors are capable of sensing mid-infrared light in the picowatt range, and the high photoresponse remains effective at kilohertz modulation frequencies, because of the fast carrier dynamics arising from BP's moderate bandgap.
Journal ArticleDOI
A Graphene-Based Resistive Pressure Sensor with Record-High Sensitivity in a Wide Pressure Range
He Tian,Yi Shu,Xue-Feng Wang,Mohammad Ali Mohammad,Zhi Bie,Qian-Yi Xie,Cheng Li,Wen-Tian Mi,Yi Yang,Tian-Ling Ren +9 more
TL;DR: A flexible, wide range and ultra-sensitive resistive pressure sensor with a foam-like structure based on laser-scribed graphene (LSG) is demonstrated, indicating that laser scribed flexible graphene pressure sensors could be widely used for artificial e-skin, medical-sensing, bio-s sensing and many other areas.
Journal ArticleDOI
Widely tunable black phosphorus mid-infrared photodetector
Xiaolong Chen,Xiaobo Lu,Bingchen Deng,Ofer Sinai,Yuchuan Shao,Cheng Li,Shaofan Yuan,Vy Tran,Kenji Watanabe,Takashi Taniguchi,Doron Naveh,Li Yang,Fengnian Xia +12 more
TL;DR: It is shown that a vertical electric field can dynamically extend the photoresponse in a 5 nm-thick BP photodetector from 3.7 to beyond 7.7 μm, opening the doors to various mid-infrared applications.
Journal ArticleDOI
Anisotropic Black Phosphorus Synaptic Device for Neuromorphic Applications.
TL;DR: The first black-phosphorus synaptic device is demonstrated, which offers intrinsic anisotropy in its synaptic characteristics directly resulting from its low crystalline symmetry, which represents an important step toward introducing intrinsic heterogeneity to artificial neuromorphic systems.
Journal ArticleDOI
Efficient electrical control of thin-film black phosphorus bandgap.
Bingchen Deng,Vy Tran,Yujun Xie,Hao Jiang,Cheng Li,Qiushi Guo,Xiaomu Wang,He Tian,Steven J. Koester,Han Wang,Judy J. Cha,Qiangfei Xia,Li Yang,Fengnian Xia +13 more
TL;DR: The unique thickness-dependent bandgap tuning properties in intrinsic black phosphorus, arising from the strong interlayer electronic-state coupling, are revealed and may pave the way for the investigation of electrically tunable topological insulators and semimetals.
