This region, occupying about 8 percent of the area of Europe west of the Urals, has often been termed the north European plain, but the title adopted in this chapter is intended to emphasize that

Excitons and Biexcitons in Semiconductors,idered. The basis of the microscopic theory and the theoretical group classification of exciton states is given. The characteristic properties of excitons are discussed in terms of the relative electron–hole and translational motion. The spin structure and the longitudinal–transverse splitting of ex

Exciton Paramagnetic, Paraelectric, and Zero-Field Resonances,addition to information about the structure of the conduction and valence bands, obtained by means of spin resonance of the conduction electrons (holes), exciton paramagnetic resonance can yield information about the exciton energy spectrum. This chapter discusses the contribution to the exciton spi

Exciton Acoustic Resonance,excitons existing in crystals. It was shown that the acoustic effects on excitons at sufficiently low concentrations are one to three orders of magnitude higher than the lattice absorption of hypersound..The contribution of free carriers to the acoustic absorption can be separated from the hypersoni
