TL;DR: In this paper, field effect transistors from single and few-layer rhenium disulfide were constructed and observed an anisotropic ratio of three to one along the two principle axes.

TL;DR: The authors' van der Waals heterojunction photodetectors not only exemplify black arsenic phosphorus as a promising candidate for MIR optoelectronic applications but also pave the way for a general strategy to suppress 1/f noise in photonic devices.

TL;DR: In this paper, a p-g-n heterostructure formed by sandwiching graphene with a gapless band structure and wide absorption spectrum in an atomically thin p-n junction was proposed for broadband photodetection in the visible to short-wavelength infrared range at room temperature.

TL;DR: A MoS2-graphene-WSe2 heterostructure for broadband photodetection in the visible to short-wavelength infrared range at room temperature that exhibits competitive device performance, including a specific detectivity of up to 10(11) Jones in the near-infrared region.

TL;DR: By performing systematic magneto-transport studies on thin films of a predicted material candidate WTe2, this work observes notable negative longitudinal magnetoresistance, which can be attributed to the chiral anomaly in WSM and demonstrates that the Fermi energy can be in-situ tuned through the Weyl points via the electric field effect.
