2D III‐nitride materials have been receiving considerable attention recently due to their excellent physicochemical properties, such as high stability, wide and tunable bandgap, and magnetism. Therefore, 2D III‐nitride materials can be applied in various fields, such as electronic and photoelectric devices, spin‐based devices, and gas detectors. Although the developments of 2D h‐BN materials have been successful, the fabrication of other 2D III‐nitride materials, such as 2D h‐AlN, h‐GaN, and h‐InN, are still far from satisfactory, which limits the practical applications of these materials. In this review, recent advances in the properties, growth methods, and potential applications of 2D III‐nitride materials are summarized. The properties of the 2D III‐nitride materials are mainly obtained by first‐principles calculations because of the difficulties in the growth and characterizations of these materials. The discussion on the growth of 2D III‐nitride materials is focused on 2D h‐BN and h‐AlN, as the developments of 2D h‐GaN and h‐InN are yet to be realized. Therefore, applications have been realized mostly based on the 2D h‐BN materials; however, many potential applications are cited for the entire range of 2D III‐nitride materials. Finally, future research directions and prospects in this field are also discussed.

“…Thus, researchers are exploring other materials with graphenelike structures and appropriate band gaps. Among these novel graphenelike materials, AlN and InN nanosheets, which belong to group III-V nitrides, have drawn extensive attention due to their excellent semiconducting property [ 18 , 19 , 20 , 21 ]. In particular, the high carrier mobility and large specific surface area of InN mean that it has great potential to be applied in the field of gas adsorption and sensing [ 22 , 23 , 24 ].…”

First-Principles Study of Au-Doped InN Monolayer as Adsorbent and Gas Sensing Material for SF6 Decomposed Species

As an insulating medium, sulfur hexafluoride (SF6) is extensively applied to electrical insulation equipment to ensure its normal operation. However, both partial discharge and overheating may cause SF6 to decompose, and then the insulation strength of electrical equipment will be reduced. The adsorption properties and sensing mechanisms of four SF6 decomposed components (HF, SO2, SOF2 and SO2F2) upon an Au-modified InN (Au-InN) monolayer were studied in this work based on first-principles theory. Meanwhile, the adsorption energy (Ead), charge transfer (QT), deformation charge density (DCD), density of states (DOS), frontier molecular orbital and recovery property were calculated. It can be observed that the structures of the SO2, SOF2 and SO2F2 molecules changed significantly after being adsorbed. Meanwhile, the Ead and QT of these three adsorption systems are relatively large, while that of the HF adsorption system is the opposite. These phenomena indicate that Au-InN monolayer has strong adsorption capacity for SO2, SOF2 and SO2F2, and the adsorption can be identified as chemisorption. In addition, through the analysis of frontier molecular orbital, it is found that the conductivity of Au-InN changed significantly after adsorbing SO2, SOF2 and SO2F2. Combined with the analysis of the recovery properties, since the recovery time of SO2 and SO2F2 removal from Au-InN monolayer is still very long at 418 K, Au-InN is more suitable as a scavenger for these two gases rather than as a gas sensor. Since the recovery time of the SOF2 adsorption system is short at 418 K, and the conductivity of the system before and after adsorption changes significantly, Au-InN is an ideal SOF2 gas-sensing material. These results show that Au-InN has broad application prospects as an SO2, SOF2 and SO2F2 scavenger and as a resistive SOF2 sensor, which is of extraordinary meaning to ensure the safe operation of power systems. Our calculations can offer a theoretical basis for further exploration of gas adsorbent and resistive sensors prepared by Au-InN.

“…So, the hybrid monolayers act as a transparent medium of light for infrared, visible and extreme UV light. 76 Optical conductivity relates the density of the current in a material with respect to the applied electric field as a function of frequency. Complex optical conductivity is closely related to the complex dielectric function.…”
