Abstract

In this paper, we study the phonon thermal properties of a LADDER NANOSTRUCTURE in harmonic approximation. We present a model consisting of two infinite chains with different masses. Then, we investigate the effect of different masses on the PHONON SPECTRUM. Moreover, as a specific case, in the absence of the second neighbor interaction, we calculate the phonon DENSITY OF STATES/MODES.Finally, we consider the thermal conductivity of the system. The results show that the PHONON SPECTRUM shifts down to the lower frequencies by increasing the masses. Furthermore, a frequency gap appears in the PHONON SPECTRUM. By increasing the springs constants, the THERMAL CONDUCTANCE decreases.
