The CoTe monolayer is found to be a semiconductor with a sizable bandgap of 0.48 eV, which is tunable using in-plane uniaxial or biaxial strains. This is because the puckered structure and intrinsic charge distribution asymmetry along the perpendicular direction enable the structure and properties to be heavily dependent on the external strain.
