Journal ArticleDOI
Graphene: The New Two-Dimensional Nanomaterial
TL;DR: The status of graphene research is presented, which includes aspects related to synthesis, characterization, structure, and properties.
Journal ArticleDOI
Monitoring dopants by Raman scattering in an electrochemically top-gated graphene transistor
Anindya Das,Simone Pisana,Biswanath Chakraborty,S. Piscanec,Srijan Kumar Saha,Umesh V. Waghmare,Kostya S. Novoselov,H. R. Krishnamurthy,Andre K. Geim,Andrea C. Ferrari,A. K. Sood +10 more
TL;DR: This work demonstrates a top-gated graphene transistor that is able to reach doping levels of up to 5x1013 cm-2, which is much higher than those previously reported.
Journal ArticleDOI
Symmetry-dependent phonon renormalization in monolayer MoS 2 transistor
Biswanath Chakraborty,Achintya Bera,D. V. S. Muthu,Somnath Bhowmick,Umesh V. Waghmare,A. K. Sood +5 more
TL;DR: Using in situ Raman scattering from a single-layer MoS2 electrochemically top-gated field effect transistor (FET), this paper showed softening and broadening of the A(1g) phonon with electron doping, whereas the other Raman-active E2g(1) mode remains essentially inert.
Journal ArticleDOI
Carbon Nanotube Flow Sensors
TL;DR: The report that the flow of a liquid on single-walled carbon nanotube bundles induces a voltage in the sample along the direction of the flow is highlighted, which highlights the device potential for nanotubes as sensitive flow sensors and for energy conversion.
Journal ArticleDOI
Graphene: The New Two‐Dimensional Nanomaterial
TL;DR: Graphene is the latest sensation with unusual properties, such as half-integer quantum Hall effect and ballistic electron transport as mentioned in this paper, and there is considerable interest in investigating two-layer and few-layer graphenes as well.
