Investigating dielectric properties and vacancy effects in bismuthene nanosheets: a Monte Carlo study
摘要
This study investigates the dielectric properties of bismuthene-like nanosheets using Monte Carlo simulations, focusing on the effects of external electric fields (Ez), linear coupling (Jσ), biquadratic coupling (K), crystal field (D), and vacancy (V) parameters. The results show that increasing the crystal field strength (|D|) and vacancy parameter (V) reduces the blocking temperature, while higher values of Ez, Jσ, and K lead to an approximately linear increase in the blocking temperature. These findings offer valuable insights into the complex interactions affecting the thermal and dielectric behavior of the nanosheets, providing new directions for future research in nanoscale materials.
