Fabrication of the α–Fe2O3 nanowires and application of the photodetector/optical switching

Hsu L.C., Li Y.Y., National Chung Cheng University, TW

In this study, we demonstrate a rapid and easy method to synthesis α-Fe2O3 nanowires (NWs). The density of the α-Fe2O3 NWs were successfully control by different thickness of Fe thin film within 10 hours by [...]

Transparent polymer photodetector to control electronic devices

Jeon K.M., Korea Advanced Institute of Science and Technology, KR

Polymer semiconductor materials are being used in variable applications such as OLED, OPV and Organic sensor, because polymer semiconductor materials have advantages like solution processing, low-cost, flexible, and easy large area fabrication. However, performance of [...]

Solar-Blind Dual-Band UV/IR Photodetectors Integrated on a Single Chip

Starikov D., Boney C., Pillai R., Bensaoula A., Integrated Micro Sensors Inc., US

Currently used flame detectors that are composed of discrete UV and IR solid-state components are bulky, sustain temperatures only below 125°C, and are not capable of detecting a multi-band optical signal with high spatial resolution. [...]

II-VI Semiconductor Quantum Wire Fabrication and Application to IR Detection

Crouse D.T., Crouse M., Crouse D.T., Crouse M., Mahapatra S., Ikram A.A., City College of New York, US

A nanoporous alumina template has been developed that provides a practical and flexible method of fabricating semiconductor and metal nanowires on any desired substrate. In situ electrochemical techniques are used to transform this multilayer precursor [...]
