Description
Jie Lu, Miaomiao Zheng, Jinxin Liu and colleagues studied how the height of atomic steps on a sapphire surface steers the growth of molybdenum disulfide in 2023. This single-layer semiconductor is grown by chemical vapour deposition for future electronics.
On low steps, the material formed neat triangular grains that grew straight across the steps. On high steps, it formed long nanoribbons instead, all aligned with the step direction and never crossing. Microscopy showed the ribbons are stitched from many grains with matching orientation. Calculations explained why: grains prefer to start at tall steps but struggle to climb them. The findings give growers a new dial for shaping the film.
