Electronics and optoelectronics of two-dimensional transition metal dichalcogenides.
TLDR
This work reviews the historical development of Transition metal dichalcogenides, methods for preparing atomically thin layers, their electronic and optical properties, and prospects for future advances in electronics and optoelectronics. Expand
Structure-Assigned Optical Spectra of Single-Walled Carbon Nanotubes
TLDR
Optical spectroscopy can be used to rapidly determine the detailed composition of bulk SWNT samples, providing distributions in both tube diameter and chiral angle. Expand
Band Gap Fluorescence from Individual Single-Walled Carbon Nanotubes
TLDR
At pH less than 5, the absorption and emission spectra of individual nanotubes show evidence of band gap–selective protonation of the side walls of the tube, which is readily reversed by treatment with base or ultraviolet light. Expand
Individually suspended single-walled carbon nanotubes in various surfactants
Individual single-walled carbon nanotubes (SWNTs) have been suspended in aqueous media using various anionic, cationic, nonionic surfactants and polymers. The surfactants are compared with respect toExpand
Structure-Based Carbon Nanotube Sorting by Sequence-Dependent DNA Assembly
TLDR
A systematic search of the ssDNA library selected a sequence d(GT)n, n = 10 to 45 that self-assembles into a helical structure around individual nanotubes in such a way that the electrostatics of the DNA-CNT hybrid depends on tube diameter and electronic properties, enabling nanotube separation by anion exchange chromatography.

Optical transition energies for carbon nanotubes from resonant Raman spectroscopy: environment and temperature effects.
This Letter reports the laser energy dependence of the Stokes and anti-Stokes Raman spectra of carbon nanotubes dispersed in aqueous solution and within solid bundles, in the energy range 1.52-2.71Expand
Electronic Structure Control of Single-Walled Carbon Nanotube Functionalization
TLDR
Diazonium reagents functionalize single-walled carbon nanotubes suspended in aqueous solution with high selectivity and enable manipulation according to electronic structure to reverse the chemistry by using a thermal treatment that restores the pristine electronic structure of the nanotube. Expand
Liquid Exfoliation of Layered Materials
Background Since at least 400 C.E., when the Mayans first used layered clays to make dyes, people have been harnessing the properties of layered materials. This gradually developed into scientificExpand
The role of surfactant adsorption during ultrasonication in the dispersion of single-walled carbon nanotubes.
TLDR
The ionic surfactant-assisted dispersion of single-walled carbon nanotubes in aqueous solution has been studied by Raman and fluorescent spectroscopy during ultrasonic processing and the former is found to be controlling with the use of a derived kinetic model for the dispersion process and extraction of the characteristic rate of nanotube isolation. Expand
Interfacial heat flow in carbon nanotube suspensions
TLDR
These findings indicate that heat transport in a nanotube composite material will be limited by the exceptionally small interface thermal conductance and that the thermal conductivity of the composite will be much lower than the value estimated from the intrinsic thermal conductivities of the nanotubes and their volume fraction.
