Computer-Assisted Determination of Peak Profiles, Intensities, and Positions

  • Chapter

Abstract

The essential prerequisite for determination of peak profiles and intensities is calibrated tunneling spectra. The first sections of this chapter will introduce a simple calibration scheme which can be implemented with any type of measurement system assisted by a minicomputer, microcomputer, or sophisticated calculator. The approach will be of a tutorial nature so that the experimenter can obtain the knowledge necessary to interface his own measurement system for use with a computer-controlled data acquisition system. Practical aspects of calibration, shortcuts, and tricks will be discussed in detail along with software-hardware tradeoffs. Following the details of calibration, the subtraction of backgrounds to IET peaks will be discussed in detail along with peak profiles in both the normal and superconducting states, from which peak intensities are easily determined The use of differential inelastic electron tunneling spectra (DIETS) will be briefly mentioned.
