Layered transition-metal dichalcogenides provide us with a most exciting area for the study of structural phase transitions that are associated with the charge density wave (CDW). A large variety of structural phase transitions, such as commensurate and incommensurate transitions, and the physical proper ties related to the formation of a CDW, have been an object of intense study made for many years by methods employing modem microscopic techniques. Rather recently, efforts have been devoted to the theoretical understanding of these experimental results. Thus, McMillan, for example, has developed an elegant phenomenological theory on the basis of the Landau free energy expansion. An extension of McMillan‘s theory has provided a successful understanding of the successive phase transitions observed in the IT- and 2H-compounds. In addition, a microscopic theory of lattice instability, lattice dynamics, and lattice distortion in the CDW state of the transition-metal dichalcogenides has been developed based on their electronic structures. As a result, the driving force of the CDW formation i | | 出版日期 | Book 1986 | | 关键词 | Atom; behavior; electron; energy; lattice dynamics; low temperature; metals; phase; phase transition; spin; st | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-4576-0 | | isbn_softcover | 978-94-010-8533-5 | | isbn_ebook | 978-94-009-4576-0 | | copyright | Springer Science+Business Media Dordrecht 1986 |
