A method of forming a nanoscale pattern on a substrate surface. In one embodiment, the method includes the steps of providing a substrate having a surface; providing a nanoscale pattern forming device, comprising an elongated cantilever that has a tip portion proximate an end of the elongated cantilever; and controllably illuminating at least the tip portion of the cantilever with a beam of substantially coherent monoenergetic particles when the cantilever moves relative to the substrate to form a nanoscale pattern on the surface, wherein the tip portion of the cantilever is made from lightly doped silicon.
摘要:
A conductive atomic force microscopy (cAFM) technique which can concurrently monitor topography, charge transport, and electroluminescence with nanometer spatial resolution. This cAFM approach is particularly well suited for probing the electroluminescent response characteristics of operating organic light-emitting diodes (OLEDs) over short length scales.
