Transfer printing techniques enabled by advanced carbon nanomaterials

Transfer printing processes comprise picking and placing operations. For objects in micro/nanosize, means to control the surface adhesion of the transfer printing tool is necessary where the strong adhesion picks up the object from a donor substrate while the weak adhesion places the object onto a target surface. In this chapter, we discuss the novel transfer printing method using vertically aligned carbon nanotubes, which utilizes an electrostatic interaction to boost the picking yield, yet has a low surface area to minimize the stiction during the placing stage.
