Description
Dong-Ho Shin and co-authors grow, in 2026, stacked layers of lead sulphide and tin disulphide one atomic layer at a time and show the stack squeezes charge carriers into quantum confinement. Thinning the lead sulphide layer below a key size widened its energy gap in steps the team could dial in.
Vibration tests showed the layers coupled strongly despite clean, strain-free boundaries, and computer models confirmed squeezing in both directions. An individually grown film sat far below the stack's tuned range. The authors say the method opens precise quantum engineering of layered materials for light-based devices.
