• application in areas such as optoelectronic applications and memory devices has been progressively unraveled. Nevertheless, new challenges with no parallel in the respective bulk material counterparts have arisen. In this review, we consider what has been achieved and what are the current limitations with

• deal of attention, due to the promising optoelectronic applications [27]. It has been shown that in order to study the donor doping and dependences of the PL intensity in such systems, it is crucial to understand and control the presence of defects. The effects of donors and defects to the PL of Si NCs
