Dear Dr. Jones,
I would like to express our appreciation for the hospitality and technical
guidance you provided to Mr. Chang during his six-month guest work
period at your laboratory. As I'm sure you know, he participated in your
re-examination of the quantized Hall effect at i=2 and i=4 plateau, and set
a new limit for the metrology of quantized Hall effect in resistance standards.
His work, under the supervision of Dr. Smith, compared different SQUID
types in CCC circuits. The paper he prepared was accepted at CPEM'94,
and this subsequently earned him a Young Scientist Award at that conference.
We believe that it was your laboratory's committment to excellence that
enabled him to have such a fruitful experience.
Mr. Chang has paved the way for closer relations between our two
laboratories. I hope that we can continue to strengthen friendship through
more such cooperative efforts. I look forward to seeing you at CPEM'95.
