Lithographic patterning
WebIt is not obvious that direct patterning with lithographic techniques is straightforward. Although perovskites are often described as “defect-resistant” due to the mobile nature of ions in the crystal, the material also has stability issues, induced by exposure to oxygen, water, or even long exposure to light. WebHere, a lithographic in-mold patterning method realized by nanocrystal concentration control and a multi-step filling-drying process is proposed to demonstrate CsPbBr 3 nanocrystals distributed-Bragg-reflector (DBR) waveguide lasers.
