Strategic Objectives
• Master the mechanics of Schottky barrier height tuning.
• Navigate the complex physics of Fermi-level pinning and interface states.
• Apply engineering strategies specifically for wide-bandgap materials like SiC and GaN.
• Transition from theoretical models to high-performance device fabrication.
The Core Challenge
Traditional metal-semiconductor interfaces often suffer from uncontrollable barrier heights and the frustrating 'pinning' of the Fermi level.
