摘要
量子点以其类似于原子的性质近年来受到很大关注.通过Stranski-Krastanow (SK)生长模式外延自组织生长的量子点具有诸多有利于红外应用的性质,例如工作温度较高、信噪比较大、暗电流较低、波段较宽以及垂直入射光响应等.对于新型红外探测器的研发而言,它们是一类很有潜力的候选者.本文主要对近期国外文献报道的量子点制备方法的部分研究进展做了总结和评述.
Quantum dots have attracted considerable interest for their atomic-like properties in recent years. The quantum dots grown by epitaxial self-assembly via Stranski-Krastanow growth mode have many favorable properties for infrared application, such as higher operational temperature, increased signal-to-noise ratio, reduced dark current, wider spectral range and sensitivity to normal incident radiation. They are potential candidates for developing a new class of infrared detectors. Some of the latest published developments in the fabrication techniques of quantum dots abroad are summarized and reviewed in this paper.
