CURRICULUM VITAE

Prof. Alferov has attended the Lindau Meeting in 2001. Due to the rotation of disciplines the Laureates will be invited every three years. The 2nd interdisciplinary Meeting was held in 2005.


Zhores Ivanovich ALFEROV was born in Vitebsk, Byelorussia, USSR on March 15, 1930. In 1947, he graduated from high school (Minsk, Byelorussia) and in 1952, he graduated from the Department of Electronics of V.I. Ulyanov (Lenin) Electrotechnical Institute in Leningrad. Since 1953 until now he has been a member of the Scientific staff of the Ioffe Physico-Technical Institute of the Russian Academy of Sciences where he consequently held the following positions: junior scientist (1953- 1964), senior scientist (1964-1967), Head of Laboratory (1967-1987), Director of the Institute (1987 - present). He received two scientific degrees: a candidate of science in technology in 1961 and a doctor of science in physics and mathematics in 1970 - both from Ioffe Institute. In 1970-1971 he spent 6 months as a visiting scientist at the University of Illinois, USA. Since 1962 he has been working in the area of III-V semiconductor heterostructures. His outstanding contributions to physics and technology of III-V semiconductor heterostructures, especially injection properties, development of lasers, solar cells, LED’s, epitaxy processes have been led to the creation of modern Heterostructure Physics and Electronics. For his achievements in this area Prof. Zh.I. Alferov was honored with many Soviet, Russian and International awards, and honorary memberships. In 1990, Zh.I. Alferov was elected a Vice-President of the Academy of Sciences of the USSR. In 1991 he was elected a Vice-President of the Russian Academy of Sciences and President of the St.Petersburg Scientific Center of the Russian Academy of Sciences. The Ioffe Institute: 2300 employees (1100 researches).

Solid State Engineering

by Adam Smith

“I didn’t anticipate it,” recalls Zhores Alferov. “I was thinking that there only would be photographs, but when he came to my country house, he proposed to me to draw something about the problems for heterostructures for which I was getting Nobel Prize! And I was just writing some important physical phenomena and applications. I mention in this picture just some applications: for lasers and some physical phenomena which I called superinjection heterostructures.”

Alferov and his fellow Laureate Herbert Kroemer were awarded one half of the Nobel Prize in Physics in 2000 for their independent creation of new semiconductors with novel properties, materials that revolutionised solid state physics and now form the basis of modern communications and information technology. Mixing different semiconductors into ‘heterostructures’ allowed them to engineer changes in electrical conductivity, giving rise to previously unseen quantum phenomena. “By the creation of very complicated compositions of different materials with very thin layers, you create material properties which do not exist in nature,” explains Alferov. He recalls that his friend Leo Esaki, also a Nobel Laureate, once remarked that these heterostructures are ‘man-made crystals’, in contrast to all other materials which he called ‘God-made crystals’.

The sketch introduces some of the concepts associated with Alferov’s discoveries. At the bottom right is a reference to two semiconductors; aluminium gallium arsenide (AlGaAs) and indium gallium arsenide (InGaAs). Above these, the word ‘heterojunction’ refers to the engineered interfaces between different semiconductors. It is the change in the allowed energy levels of electrons as they cross these junctions that give rise to heterostructures’ unique properties. Such changes in energy bands are depicted in the diagrams. In the centre, for instance, so-called ‘electron and optical confinement’ is illustrated for a double heterostructure (DHS), a sort of semiconductor sandwich now used widely in optoelectronics.

“When we started our research in the middle of the 60s,” says Alferov, “It was just a few laboratories in the world. That’s all. Now, it’s hundreds of laboratories all over the world. At any conference in semiconductor physics, practically 60-70% of talks are connected with heterostructures. So I am very happy that I started that research early and got important results … I am happy man!”
