atisfy an urgent need of many scientists working in the field ofsemiconductor physics for having al their working place a comprehensive, high quality, but inexpensive collection of at leasl the basic data of their field of interest this volume contains the most important data ofsemiconductors. All data were compiled from infannation on semil:onductors presented on more than 6 000 pages in various volumes oflhe New Series ofLandolt-Bomstein," With these words the aim of the volume "Semiconductors - Basie Data", published by the present author - was defined in the preface to its first Edition. This edition - published in two volumes in the Series "Data in Science and Technology" - appeared in 1991/92. The 2nd !-::
