Higher-ordered semiconductors have attracted extensive research interest as an adopted engineering for active solar energy harvesting, storage, and conversion. It is well-known that the effective separation and anisotropic migration of photogenerated charges are the basic driven force required for superior efficiency. However, the morphology and stoichiometric variation of these semiconductors play essential roles in their physicochemical properties of bulk and surface, especially for efficient interparticle or interfacial charge transfer. To this point, the strategy of controlling the topotactic transformation toward superstructures with optimized functionality is preferable for a wide range of optoelectronic and catalytic engineering applications. In this Minireview, we provide an overview of the crystal orientation, synthetic engineering, functional applications, and spatial and temporal charge dynamics in TiO mesocrystals and others. The viewpoint of in-depth understanding of the structure-related kinetics would offer an opportunity for design of versatile mesocrystal semiconductors sought-after for potential applications.
高阶半导体作为一种被采用的工程技术，在主动太阳能收集、存储和转换方面引起了广泛的研究兴趣。众所周知，光生电荷的有效分离和各向异性迁移是获得优异效率的基本驱动力。然而，这些半导体的形态和化学计量变化在其体相和表面的物理化学性质中起着至关重要的作用，特别是对于有效的颗粒间或界面电荷转移。在这一点上，控制具有优化功能的超结构的拓扑转变的策略对于广泛的光电和催化工程应用是可取的。在这篇综述中，我们概述了 TiO 介晶及其它介晶的晶体取向、合成工程、功能应用以及空间和时间电荷动力学。深入了解结构相关动力学的观点将为设计多功能介晶半导体提供机会，这些半导体有望应用于潜在的应用。
