Unfortunately, there was an error made in the April 2001 issue of the EDS Newsletter regarding the article entitled IEEE Members Who Received the Nobel Prize for Physics. In the write-up concerning one of the winners of the award, Zhores I. Alferov, a very vital portion of his accomplishments was inadvertently omitted, i.e. his work involving the first cw room temperature operation of a double heterojunction laser. The author of this portion of the article, Nick Holonyak, had submitted this pertinent information, but an error was made in transcribing the text from its original source. The affected portion of the write-up concerning Zhores I. Alferov's accomplishments should have read as follows:
After the semiconductor laser work of 1962, Alferov and his research group launched a large effort to realize double heterojunction devices (for superinjection and carrier and photon confinement). He was able, with the AlGaAs-GaAs system, to demonstrate the first low threshold double heterostructure lasers (1968), cw operation at room temperature (1970), high-efficiency heterojunction solar cells (1970), heterojunction p-n-p-n switches (1969), laser p-n-p-n switches (1971), high-efficiency AlGaAs heterostructure LEDs (1968), wide-gap emitter AlGaAs transistors (1972), and grating lasers with narrow beam divergence (1974). He is credited with being one of the prime instigators of the new field of heterostructure electronics, which now includes quantum well heterostructures and superlattices. His most recent work has been concerned with trying to convert the quantum-well laser with quantum-dot laser.
We sincerely apologize to both Zhores Alferov and Nick Holonyak for the error in the April issue.
