SiC devices can withstand significantly higher voltages (up to 10 times higher breakdown field strength than silicon) and temperatures, making them exceptionally robust for harsh environments. Its thermal conductivity is 3-4 times greater than silicon, which is vital for managing heavy loads in high-power applications such as electric vehicle (EV) inverters, solar inverters, and industrial motor drives. SiC semiconductors can reduce energy losses by up to 50% during power conversion, directly contributing to increased range and faster charging times for EVs. The automotive industry, in particular, has been a major driver for SiC adoption, with leading manufacturers integrating SiC into their next-generation electric powertrains, marking a clear departure from silicon-based power modules.
Beyond WBG materials, two-dimensional (2D) materials like graphene and molybdenum disulfide (MoS2) represent the ultimate frontier in miniaturization. Graphene, a single layer of carbon atoms, boasts extraordinary electron mobility—up to 100 times that of silicon—and exceptional thermal conductivity, making it ideal for ultra-fast transistors and interconnects. While early graphene lacked an intrinsic bandgap, recent breakthroughs in engineering semiconducting graphene and the discovery of other 2D materials like MoS2 (with a stable bandgap nearly twice that of silicon) have reignited excitement. These atomically thin materials are paramount for pushing Moore's Law further, enabling novel 3D device architectures that can be stacked without significant performance degradation.
