Progress in quantum computing and quantum cryptography requires efficient, electrically
triggered, single-photon sources at room temperature in the telecom wavelengths. It has …

This article reviews the electronic and transport properties of carbon nanotubes. The focus is
mainly theoretical, but when appropriate the relation with experimental results is mentioned …

The development of light-emitting diodes with improved efficiency, spectral properties,
compactness and integrability is important for lighting, display, optical interconnect, logic …

We studied the formation of the Himalayan mountain range and the Tibetan Plateau by
investigating their lithospheric structure. Using an 800-kilometer-long, densely spaced …

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 …

We observed highly efficient generation of electron-hole pairs due to impact excitation in
single-walled carbon nanotube pn junction photodiodes. Optical excitation into the second …

Light emitting field effect transistors based on molecular and polymeric organic
semiconductors are multifunctional devices that integrate light emission with the current …

We have studied the exciton properties of single-wall carbon nanotubes by solving the
Bethe-Salpeter equation within tight-binding models. The screening effect of the π electrons …

Nanomedicine utilizes the remarkable properties of nanomaterials for the diagnosis,
treatment, and prevention of disease. Many of these nanomaterials have been shown to …

Electrically driven light emission from carbon nanotubes,,,,,,, could be used in nanoscale
