研究目的
Investigating the controllable growth of high-quality inorganic perovskite microplate arrays for functional optoelectronics.
研究成果
The study successfully demonstrated a vapor-phase strategy to controllably grow high-quality CsPbBr3 microplate arrays with uniform morphology, controlled location, and size. This approach overcomes fundamental lattice mismatches and random nucleation barriers, enabling the scalable fabrication of high-performance lasers and photodetectors. The findings offer new opportunities for the development of diverse integrated optoelectronic devices.
研究不足
The fusion of adjacent droplets made dense seed patterns difficult to achieve with the present printing equipment, potentially limiting the density of microplate arrays.
1：Experimental Design and Method Selection:
The study employed a vapor-phase growth technique for CsPbBr3 microplate arrays, utilizing inkjet printing to deposit perovskite seeds on substrates to control nucleation and growth.
2：Sample Selection and Data Sources:
CsPbBr3 seeds were printed on silicon wafers and quartz glass for the growth of microplate arrays.
3：List of Experimental Equipment and Materials:
A chemical vapor deposition growth system was used for the perovskite growth.
4：Experimental Procedures and Operational Workflow:
The seeded substrates were introduced into the growth system to modulate the perovskite growth, with the growth time varied to control the microplate size.
5：Data Analysis Methods:
The crystalline quality was assessed using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), photoluminescence (PL) spectrum, powder X-ray diffraction (XRD), and transmission electron microscopy (TEM).
