The electrical characteristic test of nanowires is important in nano-materials research. The metal-semiconductor junction that is fabricated with semiconductor nanowire and metal probe in electrical test system has impact on the test result directly, therefore it's necessary to study I-V characteristics of the metal-semiconductor(M-S) junction. Si, ZnO, GaN have been selected from multiple semiconductor materials. When they connected with tungsten probe, all of them formed Schottky barriers, but the relationships between current and voltage of the junctions are distinct. In the thesis, I-V curves of these M-S junctions are compared, and the best electrical performance of M-S junction is selected.

Recently biosensors based on silicon nanowire field-effect transistors (SiNW-FETs) have drawn huge amounts of attention, due to their ultra sensitivity, selectivity, label-free and real-time detection abilities. As people know more and more knowledge of the structure and function of nucleic acid molecules, DNA detection has gained importance increasingly. Here, we briefly summarize major fabrication methods in synthesising SiNW-FETs and selectively describe some applications of SiNW-FET biosensors in DNA detection over the past few years. Some key results from each article are summarized, involving the concept and mechanism behind each sensor, with the aim of stimulating more efforts in developing SiNW-FET biosensors for detecting DNA.

The 'Information and Communication Technologies (ICT) In Motor Vehicles' Workshop was held at the Geneva International Motor Show between 4-5 March, 2009. The theme of the workshop was 'The Fully Networked Car', which focused on the integration of ICT in motor vehicles. A large number of experts, including engineers, designers, planners, government officials, regulators, and standards experts attended the event. The presentations focused on the issues facing the ICT and the automotive industries. One of the major topics discussed by the participants at the event was concerned with ICT and the impact of climate change. Some of the other topics that were discussed at the event included standards and spectrum, car-to-X communications, nomadic devices, voice and audiovisual services, advanced driver assistance systems, and wireless technologies for car production lines.
