We have observed that photoemission from single-walled carbon nanotubes saturates in
intensity as the excitation intensity increases. Each emission peak arising from specific …

Semiconductor nanowires have been used in a variety of passive and active optoelectronic
devices including waveguides, photodetectors, solar cells, light-emitting diodes (LEDs) …

In this paper we present a review on major advances achieved over the past ten years in the
field of fabrication of semiconductor quantum wires (QWRs) using epitaxial growth …

Optical gain and the Mott transition in GaAs quantum wires were studied via simultaneous
measurements of absorption and photoluminescence (PL). We observed well-separated PL …

Through an investigation of photoemission properties of highly photoexcited single-walled
carbon nanotubes, we demonstrate that there is an upper limit on the achievable excitonic …

The development of high performance p-type transparent conducting oxides (TCOs) remains
as the greatest challenge to the achievement of advanced future optoelectronics including …

We study the metal-insulator transition in individual self-assembled quantum wires and
report optical evidence of metallic liquid condensation at low temperatures. First, we observe …

We investigate the correlation effect in the quasi-one-dimensional electron-hole (eh) system
under thermal equilibrium. A self-consistent screened T-matrix approximation developed …

We study quasi-one-dimensional electron-hole (eh) systems by applying a self-consistent
screened T-matrix approximation (SSTA), which can treat an eh pair embedded in the …

Quantum condensation of electron–hole (e–h) systems in photoexcited semiconductors is
reviewed from a theoretical viewpoint, stressing the exciton Bose–Einstein condensation …
