Metal-free Janus α- and β-SiCP4: designing stable and efficient two-dimensional semiconductors for water splitting

“…24 However, these planar metal-free 2D photocatalysts have a significant drawback that is fast recombination of photogenerated electrons and holes, which limit their performance in photocatalytic water splitting applications. Fortunately, in recent years, a series of effective methods have been proposed to enhance the photocatalytic performance of metal-free 2D materials, including band engineering, 25–30 hetero-junction building, 31–33 doping, 34–37 and Janus structure building. 38–42 The Janus structure, which is essentially a unique heterojunction structure connecting multiple sublayers via chemical bonds, has shown promising results in photocatalytic water splitting due to its built-in electric field and different work functions on the top and bottom sides.…”

Two-dimensional C6X (X = P2, N2, NP) with ultra-wide bandgap and high carrier mobility

“…In addition, carrier mobility is also a crucial parameter for high-frequency and high-power electronic devices. Previous reports indicate that some of the C x P y and C x N y monolayers exhibit high carrier mobility [16,29,30]. For instance, recent theoretical work predicted a high hole mobility of ∼5.19 × 10 4 cm 2 V −1 s −1 for the CP 2 monolayer [29].…”

For instance, recent theoretical work predicted a high hole mobility of ∼5.19 × 10 4 cm 2 V −1 s −1 for the CP 2 monolayer [29]. Due to the various bonding configuration of C, N and P atoms, there is still possible to discover monolayer carbon phosphide and carbon nitride with ultra-wide bandgaps and high carrier mobility.…”
