Abstract

The fabrication of hybrid semiconducting materials comprising polymers and ceramics is a novel approach that has gained significant traction for designing multifunctional materials with improved electronic and optical properties. In this research, the design of a heterojunction hybrid material comprising polyethylene (PE) and Strontium Titanate (SrTiO₃) was explored through extensive simulations using Materials Studio. SrTiO₃ nanoparticles were dispersed in the polyethylene matrix at specific filler loadings to analyze the structural compatibility and charge-transfer phenomenon between the two constituents. The structural analysis showed increased structural compatibility and stability in the hybrid system, with improved molecular packing and reduced free volume at the interface. Electronic properties analysis revealed a heterojunction formed by the interaction between PE and SrTiO₃, which altered the band structure, reduced the energy gap, and improved charge-carrier mobility compared to pristine polyethylene.
