Science, 1 March 1996:
"Isotope Switch Toughens Transistors."
Semiconductor researchers are reaching for superlatives
to describe the discovery that a simple isotope switch
deuterium for hydrogen can improve transistor lifetimes
by factors of 10 to 50, according to a paper just
accepted at APL. The finding "has huge implications
worldwide," says Dan DiMaria of IBM.
"Mixing Nanotube Structures To Make a Tiny Switch."
Two research teams have developed a way to make an
all-carbon nanotube that behaves like a semiconductor at
one end and a metal at the other. The intersection in
the middle forms a gatelike junction that controls the
flow of electrons. In the macroworld, such gates, known
as heterojunctions, form the basis for transistors and
a host of other electronic devices. (PRL, 5 February.)
