Strategies for Fabricating Nanogap Single-Crystal Organic Transistors
Figure 7
Set of SEM images showing the fabrication steps to place and secure a C60 rod on top of pair of electrodes. From the left, a rod is selected and approached with the tungsten tip of the piezo manipulator; in situ CVD of a stripe of SiO2 allows the crystallite to be fixed onto the desired set of electrodes; SiO2 wires are deposited to hold the rod in position on the substrate, before the tip is FIB cut or simply pulled away, breaking the tip of the crystallite.
