Inverse Photoemission Spectroscopy
Abstract Inverse photoemission spectroscopy is the modern appellation of experiments which analyze the photons produced by electrons hitting a solid sample. Techniques for experiments of this kind are still developing, so in this chapter, after a historical survey in Sect.18.1, we try to give a “snapshot” of their present state. In Sect.18.2, we present the current state of the experimental instrumentation. Section 18.3 gives a short review of the work on densities of unoccupied states, making the connection to the older work in the kilo electron volt photon energy regime. Since there is a comprehensive review of this work available [18.1], we will limit ourselves in the following sections to the photon energy range below 100 eV. Band structure determinations including surface states are the topic of Sect.18.4. For results obtained with spin-polarized electrons and on semiconductors, we direct the reader’s attention to Chaps.17 and 16, this volume, respectively. In Sect.18.5, we discuss the work on unoccupied adsorbate states, which are spatially more extended than occupied states, and, therefore, more sensitive to changes in bonding etc. After a summary, we try to look forward to future developments in the exciting field of inverse photoemission, in Sect.18.6.
