Atomic Pulses Tune 2D Semiconductor Alloys for Future Quantum Materials - AZoM

This study demonstrates precise control over the composition and atomic distribution in ternary molybdenum-tungsten disulfide monolayers using sub-atomic layer deposition (sub-ALD), offering a promisi... Read original →

This sub-atomic layer deposition breakthrough for Mo-W-S TMD alloys directly addresses the scalability bottleneck in 2D semiconductor manufacturing. Technically, it offers a CMOS-compatible alternative to MBE for quantum-confined structures, spurring demand for in-situ Raman and photoluminescence metrology tools. On compliance, U.S. export controls on ALD subsystems now indirectly restrict precursor delivery hardware, exposing Taiwan, China and Hong Kong, China fabs reliant on U.S.-origin components to supply chain shocks. Strategically, TSMC and Samsung will likely fast-track proprietary 2D integration platforms, while IMEC may partner with ASML on EUV-compatible transfer processes. Within 18 months, 'atomic economy'—measured in pulse-count precision rather than angstrom-level thickness—will become a key fab evaluation metric, forcing equipment vendors to redefine deposition module standards.
