Analysis of Weighting Function in Transient Spectroscopy for Precise Measurement of Deep States
Year: 1989
Type: article
Abstract: The weighting function in transient deep-level spectroscopy has been analyzed for precise measurement of deep states. The relation among weighting functions of different measurement modes is discussed. It is shown that unless the deep energy level is a well-defined discrete one, reconstruction of the density-of-states from the observed quantity is not straightforward and the weighting function greatly depends upon the energy dependence of attempt-to-escape frequency or capture cross section of the states. Approximate and exact methods to deduce the density-of-states are presented emphasizing that the neglect of energy dependence of the attempt-to-escape frequency brings a large error in the density-of-states estimation.
