The newest developments in microelectronics, energy conversion, and sensing device design are tied very closely to our ability to selectively modify well-defined surfaces by chemical means. In particular, in the last years the passivation and functionalization of semiconductor surfaces have become a target for the realization of novel devices. We aim to develop new hybrid systems where molecular and electronic control of the structure is key. The project focus on the application of organophosphonate chemistry for covalent surface modification of emerging carbon semiconductor substrates, like silicon carbide, diamond and graphene. The applicability of organophosphonate chemistry will be further investigated with respect to generation of three-dimensional, organized multilayers, and supramolecular arrays on these substrates. Finally we aim to apply this novel approach to the optimization of nanodevices, in particular with respect to applications in biosensing.

微电子、能量转换和传感设备设计方面的最新发展与我们通过化学手段选择性地修改定义明确的表面的能力密切相关。特别是在过去的几年里，半导体表面的钝化和功能化已经成为实现新型器件的目标。我们的目标是开发新的杂交系统，其中分子和电子控制结构是关键。该项目的重点是应用有机膦化学对新兴的碳半导体衬底进行共价表面修饰，如碳化硅、钻石和石墨烯。在这些底物上生成三维、有组织的多层膜和超分子阵列方面，将进一步研究有机膦化学的适用性。最后，我们的目标是将这种新方法应用于纳米器件的优化，特别是在生物传感方面的应用。
