The demand for clean energy technologies has spurred academic interest in new and
efficient ways to capture and store sunlight. 1-6 Concerted efforts are now being directed …

Carbon nanotubes (CNTs) are nearly ideal one-dimensional (1D) systems, with diameters of
only 1–3 nm and lengths that can be on the scale of centimetres. Depending on the …

Graphene monolayer has been grown by chemical vapor deposition on copper and then
suspended over a hole. By measuring the laser heating and monitoring the Raman G peak …

A series of titanium dioxide and graphene sheets (GSs) composites were synthesized with a
sol–gel method using tetrabutyl titanate and graphite oxide (GO) as the starting materials …

Optical transitions in carbon nanotubes are of central importance for nanotube
characterization. They also provide insight into the nature of excited states in these one …

Using ultrafast optical pump-probe spectroscopy, we have measured carrier relaxation times
in epitaxial graphene layers grown on SiC wafers. We find two distinct time scales …

Quantum mechanics provides the most accurate microscopic description of the world around
us, yet the interface between quantum mechanics and biology is only now being explored …

The use of single wall carbon nanotubes (SWCNTs) as conduits for transporting electrons in
a photoelectrochemical solar cell and electronic devices requires better understanding of …

Photodetectors play key roles in many applications such as remote sensing, night vision,
reconnaissance, medical imaging, thermal imaging, and chemical detection. Several …

We report the first observation of photon antibunching in the photoluminescence from single
carbon nanotubes. The emergence of a fast luminescence decay component under strong …
