Abstract

With the advent of integrated circuits, modern electronics place increasingly stringent demands on semiconductor performance—from higher carrier mobility and thermal conductivity to better stability under extreme temperatures and high-frequency conditions. Silicon semiconductors have long dominated the industry due to their mature fabrication processes and cost-effectiveness, but in-depth exploration reveals their inherent limitations: their relatively low bandgap restricts performance in high-power applications, and they struggle to meet the speed and heat dissipation requirements of advanced technologies like 5G and beyond (e.g., 6G). This research corroborates that non-silicon alternatives—graphene (with ultrahigh electron mobility), gallium nitride (excellent for high-power/high-frequency scenarios), silicon carbide (superior thermal stability), and organic semiconductors (flexible and low-cost)—can effectively break through these technological barriers. The unique advantages of each non-silicon semiconductor have been successively demonstrated through comparative tests. Based on this study, specific performance optimization directions (e.g., optimized bandgap alignment, enhanced thermal management) that mitigate constraints in emerging fields are proposed. Delving deeper into 5G communication scenarios, parametric analyses demonstrate how these non-silicon semiconductors improve radio frequency (RF) signal transmission efficiency, enhance the sensitivity of antenna array systems, and boost power amplifier (PA) output power—while reducing energy loss.
