Sensor application of ZnO nanowires on microheater

Park J., Kim G.-T., Maeng S., Udrea F., Milne W., ETRI, KR

We fabricated the ZnO nanowire network device using sol-gel synthesis method on the pre-patterned electrode and tested the electrical property for chemical sensing. The electrodes were prepared in various ways, for example, photolithographically defined interdigitated [...]

CMOS Compatability of Carbon Nanotubes on SOI Devices

Haque M.S., Oei S.P., Teo K.B.K., Udrea F., Gardner J.W., Milne W.I., Cambridge University Engineering Department, UK

This paper reports for the first time PECVD and CVD growth of MWNTs both aligned and non aligned on high temperature partially depleted CMOS SOI substrates. We also report for the first time the growth [...]

Absorption Characteristics of Single Wall Carbon Nanotubes

Haque S., Marinelli C., Udrea F., Milne W.I., Cambridge University, UK

In this paper the absorption characteristics of Carbon Nanotube(CNT) is determined using CNT samples with varying thickness in the range of 1470-1580nm. The absorption coefficient of carbon nanotube is determined to be equal to ~24 [...]

3D Thermo-Electro-Mechanical Simulations of Gas Sensors Based on SOI Membranes

Lu C-C., Setiadi D., Udrea F., Milne W.I., Covington J.A., Gardner J.W., Cambridge University, UK

3D thermo-electro-mechanical device simulations are presented of a novel fully CMOS-compatible MOSFET gas sensor operating in a SOI membrane. A comprehensive stress analysis of a Si-SiO2ñbased multilayer membrane has been performed to ensure a high [...]
