a In-plane biaxial strain effects on the bandgap and strain energy of the GaTe/C2N heterostructure.The mistyrose, blue, and green regions represent the metal (M), Ind and D bandgap ranges, respectively. b The evolutions of the band-edge positions of the sublayers in heterostructure as a function of the in-plane biaxial strain. The I, II, and III regions correspond to type-I, -II, and -III band alignments, respectively
