Properties and potential applications of two-dimensional AlN

Two-dimensional SiC/AlN based type-II van der Waals heterobilayer as a promising photocatalyst for overall water disassociation

“…The VBM is positioned at the high symmetry K point whereas the CBM of the pristine AlN layer is at the point. This is also in line with the literature 62 , 63 . Moreover, the VBM of the free-standing AlN layer comes mainly from N p z orbital while the CBM is attributed to N s and Al s orbitals 63 .…”

Bonding, structure, and mechanical stability of 2D materials: the predictive power of the periodic table

“…168 A review covering the applications of single-layer and few-layer sheets on different substrates is available. 169 The indirect band gap of monolayer h-GaN turns into a direct gap in few-layer h-GaN. 170 Furthermore, this wide-bandgap material is a candidate for the fabrication of energy-efficient deep-UV LEDs and it is suitable for biomedical applications and photovoltaics.…”

A humidity-tolerant NO2 sensor based on Ag3PO4–SnSe2 heterostructures

“…Two-dimensional (2D) metal dichalcogenides have been actively pursued in the gas-sensing field due to their large specific surface area and outstanding electrical properties. [8][9][10] Among the family of 2D metal dichalcogenides, tin diselenide (SnSe 2 ) has shown particular potential for NO 2 sensing due to its special affinity to NO 2 molecules. 11 Moreover, SnSe 2 exhibits chemical inertness toward H 2 O molecules, which is highly desired for gas sensors to work in humid atmospheres.…”
