紫外波段氮化物半导体强耦合量子点材料与发光性能

在量子计算和量子通信领域，单光子源发挥着不可替代的作用，所以一直是该领域的重点研究方向。半导体单光子源有优良的发光性能，并且易于集成和实现电泵浦，目前被认为是理想的单光子源结构。目前已知的半导体量子点绝大多数需要在低温下工作，并且发光波长在可见光和红外光，在实际应用中有了很多限制。而III 族氮化物量子点可以在室温下工作，并且发光波长可以覆盖紫外波段，有着更广阔的前景。本数据集记录了氮化物半导体强耦合量子点在结构尺寸以及发光性能上调控的方法。实现了在紫外波段发光的氮化物半导体量子点高质量低密度生长。Single-photon sources play an irreplaceable role in the fields of quantum computing and quantum communication, and have long been a key research focus in this domain. Semiconductor single-photon sources exhibit excellent luminescent properties, are easy to integrate and enable electrical pumping, and are currently regarded as an ideal single-photon source architecture. However, the vast majority of currently known semiconductor quantum dots need to operate at low temperatures, with emission wavelengths covering visible and infrared spectral ranges, posing numerous limitations in practical applications. By contrast, Group III nitride quantum dots can operate at room temperature, with their emission wavelengths covering the ultraviolet (UV) band, thus holding broader application prospects. This dataset documents the modulation strategies for tuning the structural dimensions and luminescent properties of nitride semiconductor strongly coupled quantum dots, and achieves high-quality, low-density growth of nitride semiconductor quantum dots that emit in the ultraviolet spectral band.
