Cardiovascular diseases are a leading health concern in Hong Kong, prompting many to undergo regular heart check-ups for their early detection and management. Echocardiography, a key diagnostic imaging tool, plays a crucial role in assessing heart function, offering non-invasive insights into cardiovascular health and aiding in timely intervention. However, interpreting these ultrasound images manually is challenging due to speckle noise and ambiguous boundaries, requiring significant expertise and time. Consequently, a heart check-up is rarely included in a regular annual body check scheme.

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.

Recent theoretical research suggests that charmed baryon decays may exhibit unexpectedly large CP violation, potentially offering new clues to the matter-antimatter asymmetry in the universe. Based on the final-state re-scattering, the study predicts CP violation to be an order of magnitude larger than previous estimates. These findings highlight promising opportunities for experimental verification at current facilities like BESIII, LHCb, and Belle II, as well as the upcoming Super Tau-Charm Facility (STCF).
