KAIST team prints vertical perovskite nanolasers directly on chips
A KAIST-led research team, with collaborators from POSTECH, demonstrated an ultra-fine electrohydrodynamic 3D printing method that builds vertical perovskite nanolasers on-chip by dispensing attoliter-scale droplets. The approach produces near-single-crystalline, ultra-smooth pillar structures thinner than a human hair, improving laser efficiency and enabling height-tunable emission colors with potential uses in denser optical computing, on-chip photonics, and anti-counterfeiting.
