Abstract: The ultrasonic studies have been made in a group of materials like thulium monochalcogenides TmX (X = S, Se and Te) which are very important because TmS behaves like a metallic crystal, TmSe is intermetallic and TmTe is a semiconductor. Thus, the ultrasonic study will give a clear picture of ultrasonic attenuation in these substances. Morse potential has been used for the evaluation of second order elastic constants (SOEC) and third order elastic constants (TOEC) for TmS and TmTe which is the most appropriate method. However, Coulomb and Born Mayer potentials are the most appropriate for evaluation of SOEC and TOEC in semiconductors. Then, the Mason’s approach has been used for the evaluation of ultrasonic attenuation.
