Brookhaven
Accident Serves
As Safety Reminder
A
480-volt arc-flash event occurred at Brookhaven National
Laboratory on Friday, April 14, resulting in burn
injuries to an employee. Brookhaven is currently in
a safety stand-down as a result of this accident.
While all the details of the incident are not yet
available, it is important to reiterate to the Berkeley
Lab population that electricity provides serious and
significant hazards. A Lessons Learned will be provided
as soon as details are available. Continue to observe
all electrical safety practices and procedures in
effect at all times in an effort to avoid any such
tragic incidents at Berkeley Lab.

Lin, a scientist with the China Energy Group
in Berkeley Lab’s Environmental Energy Technologies
Division, participated in a radio discussion program
on Monday dealing with China’s environmental
policies and the U.S. role in their enforcement. Lin
was a member of a guest panel on KUOW, the PBS affiliate
in Seattle, where Chinese President Hu Jianto was
to visit beginning yesterday. To listen to a tape
of the one-hour program, go here

Semiconductors
Full of Holes?
After years of effort, a delinquent semiconductor
has been tamed. Researchers in the United States
report evidence for p-type doping of indium nitride
(InN). P-type doping introduces positively charged
conductors called "holes" into a semiconductor.
This is necessary for building devices such as solar
cells, long-wavelength lasers and fast transistors,
for which InN holds promise. But efforts to make
p-type InN have been hampered by problems with measuring
the result: surface electrons make the definitive
test impossible to carry out. Now researchers at
Berkeley Lab and Cornell University
in Ithaca, New York, have done a battery of experiments
that suggest adding magnesium to the material does
the job. (From Phys. Rev. Lett. 96,
125505, 2006).
