Nanoscience includes the study of objects and systems in which at least one dimension is 1-
100 nm. The objects studied in this range of sizes are larger than atoms and small …

Heterogeneous photocatalysis involving zinc oxide (ZnO) nanofibers (NFs) has emerged as
a new promising route for the cost-effective treatment of organic pollutants and the …

We propose a new approach to constructing gates for quantum information processing,
exploiting the properties of impurities in silicon. Quantum information, embodied in electron …

We present a theory of quantum optical control of an electron spin in a single semiconductor
quantum dot via spin-flip Raman transitions. We show how an arbitrary spin rotation may be …

Using correlated photons from parametric down-conversion, we extend the boundaries of
experimentally accessible two-qubit Hilbert space. Specifically, we have created and …

Use of nanostructured materials in powder form for various applications might show
excellent performances, however they create serious problem due to separation difficulty …

Charge excitations across an electronic band gap play an important role in opto-electronics
and light harvesting. In contrast to conventional semiconductors, studies of above-band-gap …

Progress in the synthesis of colloidal quantum dots has recently provided access to entirely
new forms of diluted magnetic semiconductors, some of which may find use in quantum …

A photoexcited II-VI semiconductor quantum dots doped with a few Mn spins is considered.
The effects of spin-exciton interactions and the resulting multispin correlations on the …

Colloidal impurity-doped quantum dots (QDs) are attractive model systems for testing the
fundamental spin properties of semiconductor nanostructures relevant to future spin-based …
