The book "Excitons in Low-Dimensional Semiconductors" provides a comprehensive examination of the role of excitons in low-dimensional semiconductors, which are central to modern semiconductor physics. The author, Stephan Glutsch, develops the effective mass theory of excitons and explains numerical methods for calculating optical absorption while considering Coulomb interactions, geometry, and external fields. The theoretical concepts are applied to specific phenomena such as Fano resonances and Zener breakdown in superlattices. The book is clearly structured and offers a practical approach with detailed derivations, examples, illustrative figures, and computer programs. It is aimed at students, educators, and researchers who wish to engage with advanced topics in semiconductor physics.
