Published in the Journal of Applied Physics…

Well, I’m finally published in my current field.  It took a very very long time to get this paper published.  All sorts of reasons for the delay.  In fact, this work was originally started in 2004  (our first bicrystal was successfully grown in ’04).  During research group meeting, I made an under the breath comment something akin to: “Well, darnit, it’s too bad we can’t study a single grain-boundary, because then everything would be so much easier…”  Prof. Rockett looked over to me and smiled: “But, Allen, we can study a single grain-boundary!  That’s a great idea!”  So, the bicrystal project was started.

We were able to obtain a bicrystal GaAs wafer from Wafer Technology Limited Co. (UK); I requested a bad growth, with crystallites as large as possible.  I’ll be forever indebted to the great guys at Wafer Technology for their quick grasp of what I was looking for.  After visiting our group in 2006, S. Seibentritt at HMI (now at Lüxenbourg) started similar work.

While this current paper isn’t perfect, it went through numerous revisions.  Most of the extensive EBSD calculations didn’t make the paper.  Subsequent papers will likely revisit the disorientation discussion.

Unfortunately, there was an error we missed in the proof.  The paper is currently missing Figure 2(c): The cross-sectional HRTEM image (the hard work of C. Lei).  The image can be found here: Cross-Sectional HREM image of Cu(In,Ga)Se2 bicrystal, hosted at Prof. Angus Rockett’s research group’s webpage.

A Quick Introduction...

I'm a graduate student (PhD Candidate) at the University of Illinois at Urbana-Champaign.

I've studied and researched in two fields of Materials Science and Engineering (Polymers and Semiconductors). My interests are as diverse as my musical tastes and I usually have my hand in some crazy project during my free time.

I'm available for consulting and have access to a world-renown materials research user-facility supported by the D.O.E. If you would like to know more, please contact me.
