Abstract
Disclosed are methods to prepare a specimen for microanalysis, the specimens so prepared, and methods to analyze the specimens by atom probe microscopy. The specimens are prepared by embedding a specimen within an electrically conductive matrix to yield an embedded specimen; and then forming regions on the embedded specimen into shapes suitable for microanalysis by an atom probe.
Claims28
A method of preparing a specimen for microanalysis, the method comprising:
- (a) embedding the specimen within an electrically conductive polymer matrix to yield an embedded specimen;
- and
- (b) forming regions on the embedded specimen into shapes suitable for microanalysis by an atom probe.
A composition of matter comprising an intrinsically conductive polymer whose conductivity has been altered by contact with a compound selected from a group consisting of osmium tetroxide, ruthenium tetroxide, and combinations thereof.
