Abstract

In this study, we have investigated the thermodynamic properties of the polar quantum disc having conical disclination. The spectrum of the non-interacting charged particle system was obtained with the aid of the Schrödinger equation with the effective mass approximation. The charged particle under investigation is confined by parabolic potential and a homogeneous magnetic field perpendicular to the quantum disc. We have shown the variation of internal energy (U) and specific heat Cv with the kink parameter α. Both U and Cv increase with the increase in α.
