Abstract
Incorporating metal nanocrystals into the interface is an effective approach to improve the performance of the nanoheterojunctions. Through combining the direct current magnetron sputtering technique and solvothermal method, the Cd nanocrystals have easily and efficiently been incorporated into the CdS/Si nanoheterojunctions (CdS:nc-Cd/Si). From the study of photoluminescence and electrical properties, it can be concluded that the incorporation of Cd nanocrystals into the interface of CdS/Si nanoheterojunctions can facilitate the improvement of carrier separation and transportation. It is believed that the devices based on CdS:nc-Cd/Si and CdS/Si nanoheterojunctions can be potentially applied in the optoelectronic fields by optimizing the preparation conditions. This study can provide the experimental and theoretical supports for the development of heterojunction devices.
