Quantum dots (QDs) or semiconductor nanocrystals are semiconductor particles a few nanometres in size with optical and electronic properties that differ from those of larger particles via quantum mechanical effects. They are a central topic in nanotechnology and materials science.
Alexey Ekimov or Aleksey Yekimov [1] (Russian: Алексей Екимов; born 1945) is a Russian [2] 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.
He coined the term quantum dots, [4] for demonstrating the first zero-dimensional electronic device that had fully quantized energy states. Reed did research in electronic transport in nanoscale and mesoscopic systems, artificially structured materials and devices, molecular electronics, biosensors and bioelectronic systems, and nanofluidics.
1988 – Giant magnetoresistance is discovered by Albert Fert and Peter Grünberg. 1988 – The conductance quantum are first demonstrated in quantum point contacts. [92] 1991 – Carbon nanotube are discovered by Sumio Iijima; 1995 – Experimental Bose–Einstein condensate is first demonstrated by Eric Cornell, Carl Wieman and Wolfgang Ketterle.
He is a leading figure in the research and development of quantum dots. [8] Quantum dots are tiny semiconducting crystals whose nanoscale size gives them unique optical and electronic properties. [19] A major challenge in quantum dot research was to find ways to create high quality quantum dots that are stable and uniform. Bawendi is recognized ...
Scientists have officially spotted characteristics of superfluidity (a quantum fluid with zero viscosity) inside a two-dimensional supersolid for the first time.
Researchers have discovered that it’s possible to speed up, slow down, or reverse the flow of time in a quantum system. Researchers have discovered that it’s possible to speed up, slow down ...
Efros is the co-discoverer of semiconducting nanocrystals known as quantum dots. [1] Efros graduated as a physical engineer in 1973 from the Leningrad Technological Institute and received his doctorate there in 1978. He was a scientist at the Ioffe Institute in Leningrad from 1981 to 1990, at which time he moved to the West. [1] [2]
