An application of lattice fringe visibility theory to the study of ordered particle growth on nanocylinders is described in this paper on ‘Lattice fringe signatures of epitaxy on nanotubes’ to cond-mat/0603312. These model predictions are easy (if tedious) to test against angle/position measurements of fringes from individual particles. Digital darkfield techniques provide an alternate way to compare model and experiment. Atom scale tunnels through a crystal become easier and easier to see as the crystal becomes thinner and thinner. This paper examines these effects for crystals in the 2 to 30 nm size range, both experimentally and theoretically working toward rules which allow one to predict quantitatively how crystal size and orientation alter the lattice fringes seen in an electron microscope. The result: Ball-shaped fringe visibility maps that allow one to answer a whole bunch of quantitative questions./pf 2005jan31 Copyright (2005) American Institute of Physics (AIP), this article may be downloaded for personal use only.

In context of this paper, here are a bunch of online-interactive fringe visibility and Kikuchi maps. Let us know if you find errors, or have other structures you’d like to see mapped. This paper considers how nano-humans might determine the 3D structure of crystals, if they were able to re-orient the crystal in their hand while trying to peer down along tunnels between the columns of atoms which run in various directions. In that case, they could formulate rules (protocols) for everyone to use in recognizing a face-centered cubic crystal, a body-centered cubic crystal, etc. Precisely this type of manipulation (imagine a hand which can only tilt the crystal through a limited angle, over one or two fixed axes) is becoming increasingly possible with modern day atomic resolution transmission electron microscopes. It is therefore time to summarize and refine strategies, including those discussed here./pf 2002oct02 Elsevier’s published version is available through ScienceDirect, but posted with permission here only in the Book section of our limited-access Nanoscale Science and Technology Blackboard. A subset, and often the whole, reciprocal lattice of a crystal can be inferred from the xyz coordinates of three non-coplanar reciprocal lattice vectors. Such coordinates may be obtained from electron-phase or Z contrast images taken at two tilts, provided that one image shows two non-colinear lattice periodicities, and the other shows a periodicity not coplanar with those two. We show here how to find, and implement, protocols for measuring the 3D parameters of any lattice type in this way. Particularly for cubic crystals with cell side greater than twice the appropriate resolution limit, we show that orthogonal +/-15 and +/-10 degree tilt ranges may allow one to measure 3D parameters of all varieties in a specimen, from only two well-chosen images. The strategy is illustrated by measuring the lattice parameters of a 10nm WC_{1-x} crystal in a plasma-enhanced chemical-vapor-deposited thin film.
