Radiofrequency sensing systems based on emerging two-dimensional materials and devices

Abstract

As one of the most promising platforms for wireless communication, radiofrequency (RF) electronics have been widely advocated for the development of sensing systems. In particular, monolayer and few-layer two-dimensional (2D) materials exhibiting extraordinary electrical properties not only can be integrated to improve the performances of RF circuits, but also to display exceptional sensing capabilities. This review provides an in-depth perspective of current trends and challenges in the application of 2D materials for RF biochemical sensing, including: i) theoretical bases to achieve different sensing schemes; ii) unique properties of 2D materials for reasoning their applications in RF sensing; iii) developments in 2D RF sensors to facilitate the practice of biochemical sensors with ever-demanding sensitivities, as well as their potential uses in meeting the requirements and challenges of biochemical sensors in the Internet-of-Things (IoT) era.

Preparation of MXene-based hybrids and their application in neuromorphic devices

“…Moreover, 2D nanomaterials could be stacked through molecular interaction to obtain properties beyond the pristine components [23][24][25]. As a new group of 2D nanomaterials, MXenes have been widely and extensively explored for new field applications [26][27][28]. Partially, MXenes-based memristors have become a hot research topic to date [15,[29][30][31][32].…”

Photodetectors Based on ZrS3/MoS2 Heterostructures

“…Photodetectors based on two-dimensional (2D) materials are a rapidly developing field of optoelectronics that offer a range of promising applications in areas such as imaging, sensing, and communication. − These detectors are thin and lightweight, making them suitable for use in a variety of scenes, including wearable electronics and satellite imagery. In comparison with photodetectors based on traditional semiconductors (e.g., Si, GaAs, InGaAs, etc.…”
