Modification of silicon based nanowires by selective self-limiting surface reactions

该项目的重点是纳米线的适当表面修饰，这是设备组装和特定功能所需的。在该项目的第一部分中，研究了纳米线器件的广泛制造程序，重点是生物传感器器件。此外，我们还利用ALD技术构建了p型Si/n型二氧化钛纳米线结构，并将其用于传感浓度为200 nm的重要神经递质多巴胺。目前的研究集中在利用表面修饰的纳米管来改进生物传感器，这为增强生物化学传感提供了多种可能性。

The project focuses on suitable surface modifications of nanowires, which are required for device assembly and specific functionality. Within the first part of the project the extensive fabrication routines of nanowire devices were studied with emphasis to bio-sensor devices. Furthermore, a ptype Si / n-type TiO2 nanowire structure was created by means of ALD and used to sense the important neurotransmitter dopamine down to a concentration of 200 nM. The current research focuses on bio-sensor improvements by using surface modified nano-tubes, which offer versatile possibilities for enhanced bio-chemical sensing.
