The Development of Semiconductor Heterostructures: The Basis of the Revolution for Today's Technological Age
Professor Zhores Ivanovich Alferov (Nobel Laureate, Physics, 2000)
Our enjoyment of everyday technology such as mobile phones and satellite TV would be impossible without the development of the advanced technology, underpinned by the developments in the physics of semiconductor heterostructures, seen in recent years.
The double heterostructure (DHS) laser is now found within every CD and DVD players, and heterostructure solar cells have also been widely used for space and terrestrial applications. This technology is one of the most exciting frontiers of modern nanotechnology as it impacts on everyone of us in the devices that we use every day and on solving future energy needs, for example. Semiconductor heterostructures provide excellent opportunities for improving the absorption of infrared radiation in photovoltaic devices, which accounts for half of the power in the solar spectrum.
Solid state physics has been enormously influenced by semiconductor heterostructures, while double heterostructures including quantum wells, wires and dots (which have been studied as agents for medical imaging, quantum computing and solar cells) constitute two-thirds of the research of the entire semiconductor physics community, emphasizing the importance of the subject to researchers today.
In his lecture Professor Alferov will consider the history of semiconductor research from its genesis to today and beyond looking at a variety of different structures available today and for use in a wide range of applications.
He will pay special attention in his lecture to future trends of major technological significance: quantum dot structures and the general problems of the creation of defect-free structures based on III-V-nitrides. One of the most important future uses of semiconductor heterostructures will be in the field of solar energy: photovoltaic solar energy conversion and a possible solution to the energy needs of the developing world.
