ㅁ초록:

Two-dimensional (2D) semiconductors, such as transition metal dichalcogenides (TMDs), have emerged as promising channel materials for beyond-CMOS electronics owing to their atomically thin bodies, excellent electrostatic control, and strong immunity to short-channel effects at the ultimate scaling limit. Beyond device scaling, their van der Waals layered nature and low thermal budget make them particularly attractive for back-end-of-line (BEOL)-compatible monolithic 3D (M3D) integration.

In this talk, I will discuss the opportunities and challenges of employing 2D semiconductors as post-silicon channel materials for future CMOS technologies and BEOL-compatible M3D integration. Particular emphasis will be placed on the key material and device bottlenecks that currently limit their large-scale adoption, including doping, contacts, and dielectric integration. Finally, I will highlight recent advances from our group that address these challenges through remote modulation doping, pinning-free contacts, and engineered gate stacks for high-performance 2D electronics.
