Semiconductor superconductors

Geake, Elisabeth
June 1991
New Scientist;6/15/91, Vol. 130 Issue 1773, p23
Focuses on the claims of physicists at the University of California in Berkeley, who state that they have discovered a superconducting semiconductor after seeing evidence of superconductivity in gallium arsenide. Unsuccessful attempts of physicists in the US to reproduce the experiments; Comment of Bob Cava of AT&T Bell Labs in the US.
