Korean food delivery system is renowned to be fast and efficient. Scooters speed through the city to bring orders timely to your doorstep. Researchers have now developed a low-temperature reaction, where a “chemical scooter delivery” can be used as a metaphor. A “sodium-scooter”, namely Na2Te, transports tellurium to molybdenum disulfide (MoS2) and tungsten disulfide (WS2) monolayers. With the help of the scooter, sulfur atoms were replaced with tellurium. The process occurs at 525 °C, about 300 °C lower than previously achievable. This study is expected to facilitate the exploration of new properties in these 2D materials.
