About this Research Topic
Perovskite single crystals have different morphologies: bulk single crystals, micro single crystals, single crystal thin films, single crystal wire/plate, etc. The optoelectronic applications of perovskite single crystals correlate intimately with their morphology. For example, centimeter-sized perovskite bulk single crystals are ideal candidates for high-energy radiation detection due to their superior optoelectronic properties, large thickness and the existence of heavy atoms. However, their thickness is far greater than the carrier diffusion length, causing ineffective carrier transport and collection. To overcome the obstacle, single crystal thin film with a thickness similar to the carrier diffusion length should be developed.
This Research Topic focuses on perovskite single crystals, including growth, fundamental understanding, and optoelectronic applications. We encourage researchers working in these fields to submit their latest Original Research, Mini Review, or Perspective articles dealing with themes that include, but are not limited to:
• Synthesis of lead-free perovskite single-crystal materials
• Morphology control of perovskite single crystals: bulk single crystals, single crystal thin film, single crystal wire/plate, microcrystal, etc.
• Understanding of the fundamental properties of perovskite single crystals
• Perovskite single crystal photodetectors
• Perovskite single crystal solar cells
• Perovskite single crystal high energy radiation detectors
• Perovskite single crystal field effect transistors
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
