“…The oxidation and reduction reactions which take place at the surface of S2 and S1, respectively, are helpful for separation of the photogenerated electrons and holes. Ever since graphene (G) unlocked the eld of 2D materials because of its excellent properties, [13][14][15][16][17][18][19][20][21][22][23][24][25] other 2D materials, such as transition-metal dichalcogenides (TMDs) [26][27][28] and phosphorene, [28][29][30] have also attracted wide attention. In particular, blue phosphorus (BlueP), a G-like material, has been a subject of investigations owing to its wide fundamental bandgap, 31 stable honeycomb structure, 32 high mobility, 33,34 and novel thermal and thermomechanical characteristics.…”
