Abstract	The continuous expansion of artificial intelligence, scientific simulation, cloud computing, edge computing, and data-intensive applications is creating unprecedented demands for computational performance, energy efficiency, memory bandwidth, and thermal management. Conventional silicon-based semiconductor technologies remain the foundation of modern computing, but physical scaling limitations and increasing power densities are encouraging research into advanced semiconductor materials and heterogeneous computing architectures. Materials such as gallium nitride (GaN), silicon carbide (SiC), gallium arsenide (GaAs), indium phosphide (InP), two-dimensional materials, graphene, carbon nanotubes, and emerging wide-bandgap and ultrawide-bandgap semiconductors offer potentially significant advantages for specialized computing and electronic applications. This study examines the role of advanced semiconductor materials in shaping the future of high-performance computing (HPC). It evaluates material properties, emerging fabrication approaches, heterogeneous integration, advanced packaging, thermal management, and their potential applications in AI accelerators, high-bandwidth computing, photonic interconnects, and energy-efficient data centres. A qualitative comparative methodology based on academic literature and technology reports is employed. The analysis indicates that no single material is likely to replace silicon across the entire computing ecosystem. Instead, future HPC systems are expected to combine silicon with specialized semiconductor materials according to workload, frequency, power, thermal, and interconnect requirements. Challenges including manufacturing complexity, defect density, wafer-scale integration, cost, supply-chain constraints, and compatibility with established semiconductor processes remain significant. The study concludes that advanced materials, combined with chiplet architectures, 3D integration, advanced packaging, and heterogeneous computing, will be central to the development of future high-performance and energy-efficient computing systems.
