Abstract

One objective of the present work is to study the processes of assembly/self assembly of diamond clusters into nanostructures such as dots, wires,and filmsunder the influence of high electric fields. Diamond nanoparticles (∼2-5 nm in size) in a suspension of ethyl alcohol were deposited by pulsed electrophoresis onto sharp metal needles, such as those employed for field electron emission applications [1,2]. A custom designed sample holder has been constructed for a JEOL 2010 F, which allows for the convenient transfer of the sharp metal wires for analysis at high resolution, and then for removal (e.g. for re-deposition). These procedures allow us to precisely control the deposition thickness and morphology. They are capable of building a variety of deposition structures, even an isolated nanodiamond particle. The geometry of the deposits depends upon the applied voltage, the concentration of the suspension, the pulse duration, and the local electric field (which in turn depends on tip geometry, e.g. see Fig. 1).
