The research team led by Professor Jun He from Wuhan University has developed a universal metal-assisted epitaxy strategy to produce wafer-scale monolayer MoS₂ films with specific substitutional doping on commercial insulator substrates of c-plane sapphire. By precisely introducing dopants, the carrier types of monolayer MoS₂ films can be effectively modulated, evidenced by the theory calculations and multi-scale characterizations. Consequently, transistors with high mobility (≈ 71.2 cm²V⁻¹s⁻¹) and on/off current ratio (≈ 10⁸), as well as low-power inverters, are obtained. Finally, we developed a standard gate-last process for integrating hundreds of thousands of gate level modulation-doped MoS₂ array devices on a 4-inch wafer, and demonstrated their applications in digital logic circuits such as data selector, 3-to-8 decoder and full adder. These results advance the development of controllable synthesis technology for wafer-scale 2D modulation-doped semiconductors and pave the way for their practical applications in integrated electronics.
