Professor Alferov ist Physiker und forscht im Bereich der Halbleiterlaser. Er erhielt im Jahr 2000 den Nobelpreis für Arbeiten in der Halbleiterphysik, die Basis moderner Informationstechnologien sind.
Abstract
The discovery of the transistor formed the basis for the development of semiconductor electronics in the 20th century. In turn, the discovery itself was based on fundamental semiconductor research: Wilson’s band theory, the contact phenomena theory of Shottky and Davydov, photoeffect and tunnelling research of Frenkel and Ioffe. Rapid development of information technologies in the second half of the 20th century mostly relies on silicon microelectronics and semiconductor heterostructures optoelectronics. The progress of the silicon “chips” technology brightly illustrated with Moore’s law has resulted in huge microprocessors and computer progress. The development of semiconductor heterostructures has led to the current state of fiber-optics communication, the use of cell phones, CDs, LED lighting and provided a whole laboratory for creation and research of low dimensional electronic gas structures.
Today’s birth of nanoelectronics, however, brings forth a problem of setting principal limits for the further compliance with Moore’s law. It leads to the origination of new branches of electronics: spintronics, molecular electronics, and quantum logic require decades of research and development. The integration of semiconductor heterostructure photonics with silicon chips will probably become the most promising of its new stages.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
