Application of Glass Capillaries with an Outer Diameter of Less Than One Micrometer in a Manipulator Made Based on an Atomic Force Microscope
摘要
Abstract
The use of glass capillaries with an outer diameter at their sharp end of less than 0.3 μm as probes in a manipulator based on an atomic force microscope (AFM) operating in a dynamic full-contact mode is considered. Various aspects of setting up the feedback system in this mode of AFM operation were studied to correctly obtain an image of the topography of the sample under study. Examples are given of the use of capillaries as probes for moving nanowhiskers with a characteristic diameter of 100 nm and hexagonal boron nitride (hBN) flakes with characteristic sizes from units to hundreds of micrometers. The possibility of creating and moving liquid droplets with a volume of less than 100 attoliters has been demonstrated.
