TL;DR: It is demonstrated that exceptionally efficient broadband modulation of terahertz waves at room temperature can be realized using graphene with extremely low intrinsic signal attenuation, which is also the first demonstrated graphene-based device enabled solely by intraband transitions.

TL;DR: In this paper, the authors reported the realization of field effect transistors (FETs) made with chemically synthesized layered two dimensional (2D) crystal semiconductor WS2, which demonstrated ambipolar behavior and a high (~105x) on/off current ratio at room temperature with current saturation.

TL;DR: In this article, the authors reported the realization of field effect transistors (FETs) made with chemically synthesized multilayer crystal semiconductor WS2, which demonstrated ambipolar behavior and a high (∼105×) on/off current ratio at room temperature with current saturation.

TL;DR: The TC of GNRs is an order of magnitude lower than that of micron-sized graphene on SiO(2), suggesting strong roles of edge and defect scattering, and the importance of thermal dissipation in small GNR devices.

TL;DR: Transient absorption microscopy was employed to image charge carrier dynamics in epitaxial multilayer graphene, and significant spatial heterogeneity in the dynamics was observed due to differences in coupling between graphene layers and the substrate.
