Piezoresistivity in nanocrystalline graphene

在这个项目中，纳米晶体石墨烯（NCG）作为透明应变传感器的基础进行了研究。起点是一个理论工作，它预测石墨烯中的压电阻率可以通过一定的晶界来增加。到目前为止，这种效应还没有在实验文献中描述，但根据预实验结果，这种效应似乎是存在的。结合实验和理论方法，目的是阐明晶界、功能化和能带结构效应对NCG压电阻率的影响。

In this project nanocrystalline graphene (NCG) is examined as a basis for transparent strain sensors. The starting point is a theoretical work, which predicts that piezoresistivity in graphene can be increased by certain grain boundaries. Up to now, this effect is not described experimentally in the literature, but appears - according to pre-experimental results - to be existent. Combining experimental and theoretical methods the goal will be to clarify the influence of grain boundaries, functionalisation and band structure effects on piezoresistivity in NCG.
