Graphene and 2D Material-Based Photodetectors

Dear Colleagues,

Recently, photodetectors have generated intense interest and have been widely applied in various fields, such as sensing, monitoring, imaging, and detecting. Various types of photodetectors have been developed based on traditional semiconductor materials and other novel two-dimensional materials. Two-dimensional materials have gained significant attention as active materials in these devices since their optical and electronic properties can be tailored for specific photodetection applications. On the other hand, the combination of novel fabrication strategies and theoretical simulation further uncovers the working mechanism of the as-fabricated photodetectors based on two-dimensional materials. In addition, these photodetectors exhibit several advantages, including high sensitivity, fast response, low noise, tuned spectral absorption, and low-cost production. These advantages highlight the potential of two-dimensional materials to advance the performance and efficiency of photodetectors for various industrial and scientific applications.

This Special Issue aims to present comprehensive research on the recent progress in photodetectors based on graphene and two-dimensional nanomaterials and further extend the potential applications of these photodetectors. This includes the fabrication of novel two-dimensional materials, as well as the adjustment of their optoelectronic properties, the construction of new kinds of device structures, the optimization of the photo-response performance based on both experimental and theoretical investigations, and the extension of the potential applications of photodetectors based on two-dimensional nanomaterials.

In this Special Issue, original research articles, communications, and reviews are welcome. Research areas may include (but are not limited to) the following:

• Synthesis of novel two-dimensional materials with controlled morphology and composition via different fabrication techniques;
• Homo- or hetero-junction two-dimensional materials;
• Experimental and theoretical investigations of the optoelectronic properties of two-dimensional materials;
• Photo response performance studies of various two-dimensional materials;
• Design and optimization of the device architectures and interfaces using two-dimensional nanomaterials;
• Exploration of the potential applications of photodetectors based on two-dimensional nanomaterials, such as in biomedical imaging, environmental monitoring, and telecommunications.
