Band Structure Engineering in Semiconductor Microstructures [Paperback]

This volume contains the proceedings of the NATO Advanced Research Workshop on Band Structure Engineering in Semiconductor Microstructures held at Il Ciocco, Castelvecchio Pascali in Tuscany between 10th and 15th April 1988. Research on semiconductor microstructures has expanded rapidly in recent years as a result of developments in the semiconductor growth and device fabrication technologies. The emergence of new semiconductor structures has facilitated a number of approaches to producing systems with certain features in their electronic structure which can lead to useful or interesting properties. The interest in band structure engineering has stimd ated a variety of physical investigations and nove 1 device concepts and the field now exhibits a fascinating interplay betwepn pure physics and device technology. Devices based on microstruc? tures are useful vehicles for fundamental studies but also new device ideas require a thorough understanding of the basic physics. Around forty researchers gathered at I1 Ciocco in the Spring of 1988 to discuss band structure engineering in semiconductor microstructures.Electronic Structure, Band Offsets and Stability.- Comments on Can band offsets be modified controllably?.- The pressure dependent band offset in a type II superlattice, a test for band line-up theories.- Electronic properties of semiconductor interfaces: the control of interface barriers.- Polar/polar, covalent/covalent and covalent/polar semiconductor superlattices.- Band offsets at semiconductor heterojunctions: bulk or interface properties?.- The physics of Hg-based heterostructures.- Valence band discontinuities in HgTe-CdTe-ZnTe heterojunction systems.- Exact envelope function equations for microstructures and the particle in a box model.- A method for calculating electronic structure of semiconductor superlattices: perturbation.- The effects of ordering in ternary semiconductor alloys: electronic and structural properties.- Ab-initio molecular dynamics stlcC
