Alexey Ivanovich Ekimov (Russian: Алексей Иванович Екимов; born 1945) is a Russian[1] solid state physicist and a pioneer in nanomaterials research. He discovered the semiconductor nanocrystals known as quantum dots in 1981, while working at the Vavilov State Optical Institute.[2][3][4]

Education and career

Ekimov was born in the Soviet Union. In 1967, he graduated from the Faculty of Physics, Leningrad State University. He went on to receive his PhD in physics at the Ioffe Institute of the Russian Academy of Sciences. After graduation, Ekimov moved to the Vavilov State Optical Institute to conduct research.[4]

In 1981, Ekimov, along with Alexei A. Onushchenko, reported the discovery of quantum size effects in copper chloride nanocrystals in glass.[5] The phenomenon was further investigated in subsequent work with Alexei L. Efros.[6][7]

Since 1999, Ekimov has been living and working in the United States as a scientist for Nanocrystals Technology, a company based in New York State.[8][9]

Honors and awards

Ekimov was awarded the 1975 USSR State Prize in Science and Engineering for work on electron spin orientation in semiconductors.[4] He is co-recipient of the 2006 R. W. Wood Prize of the Optical Society of America for "discovery of nanocrystal quantum dots and pioneering studies of their electronic and optical properties" shared with Alexander Efros and Louis E. Brus.[10]

Ekimov, Brus and Moungi Bawendi were the recipients of the 2023 Nobel Prize in Chemistry "for the discovery and synthesis of quantum dots".[9][11]
