Innovation Summary:
This invention discloses a novel class of monolayer transition metal dichalcogenides (TMDs) that exhibit giant valley-polarized Rydberg excitons, as revealed through magneto-photocurrent spectroscopy. The materials demonstrate strong excitonic effects and valley polarization under magnetic fields, enabling precise control over quantum states in 2D semiconductors. These properties are critical for advancing valleytronic and quantum optoelectronic applications. The technique also provides a powerful tool for probing excitonic states in low-dimensional materials with high sensitivity.

Challenges / Opportunities:
Traditional semiconductor materials lack the ability to support valley-polarized excitons with high binding energy and tunability. This invention addresses the need for materials that can operate under quantum-confined conditions with enhanced optical and electronic properties. It opens opportunities for developing next-generation quantum devices, including valleytronic transistors, quantum sensors, and optoelectronic modulators. The approach also enhances fundamental understanding of exciton dynamics in 2D materials.

Key Benefits / Advantages:
