Nanophotonic Device Using ZnO Nanostructures

Nanophotonic Devices Based on Semiconductor Quantum Nanostructures

In this study, our recent research activities on nanophotonic devices with semiconductor quantum nanostructures are reviewed. We have developed a technique for nanofabricating of high-quality and high-density semiconductor quantum dots (QDs). On the basis of this core technology, we have studied next-generation nanophotonic devices fabricated using high-quality QDs, including (1) a high-perform...

A nanophotonic solar thermophotovoltaic device.

The most common approaches to generating power from sunlight are either photovoltaic, in which sunlight directly excites electron-hole pairs in a semiconductor, or solar-thermal, in which sunlight drives a mechanical heat engine. Photovoltaic power generation is intermittent and typically only exploits a portion of the solar spectrum efficiently, whereas the intrinsic irreversibilities of small...

Hydrothermal growth of ZnO nanostructures.

One-dimensional nanostructures exhibit interesting electronic and optical properties due to their low dimensionality leading to quantum confinement effects. ZnO has received lot of attention as a nanostructured material because of unique properties rendering it suitable for various applications. Amongst the different methods of synthesis of ZnO nanostructures, the hydrothermal method is attract...

ZnO – nanostructures , defects , and devices

The interest in ZnO structures has increased drastically in recent years. Intense research by many different groups has focused on novel nanostructures with different shapes ranging from nanowires to nanobelts and even nanosprings. The number of reviews on ZnO is increasing (see for example1-9). The topic of p-doping is especially difficult and has been investigated by different groups10-13. Zn...
