Investigating the dielectric characteristics of a nanostructure resembling sumanene through Monte Carlo simulations

This work explores the dielectric behaviour of a nanostructure resembling Sumanene via Monte Carlo methods, focusing on ground state phase diagrams for mixed spins at different physical conditions using the Blume-Capel Ising model. The blocking temperature (TB) behaviour was examined under varying exchange coupling interactions and crystal and external electric fields. Hysteresis loops were analysed under the variation of exchange coupling interactions, temperature, and crystal field, revealing multiple polarisation plateaus and loops. These findings highlight the complex interplay between temperature, coupling parameters, and external fields in shaping dielectric behaviour, which was crucial for designing high-performance capacitors, memory devices, sensors, and transistors, advancing next-generation nanoscale dielectric materials.
