Abstract
The major findings of the research work are being given as following:
The simple interaction potential model for the calculation of temperature dependent second and third order elastic constants is validated for the nanowires of different diameters. Theoretical approach for the determination of ultrasonic attenuation in NWs at 300 K with different diameters is established. There is strong correlation between size dependent ultrasonic attenuation and size dependent thermal conductivity of the nanowires. Thus an ultrasonic attenuation mechanism is established as to extract the important information about the microstructural phenomena like phonon-phonon interaction in the NWs and thermal conductivity behavior with respect to diameters of NWs at 300 K.
