a,b) Surface plot of valleys around VBM and CBM for the ph‐ZnSe and the t‐ZnSe monolayers, respectively. Computed effective mass of electrons and holes for MoS₂, ph‐ZnSe and t‐ZnSe monolayers are given in Table 1, where k_a and k_b refer to directions Γ → X and Γ → Y, respectively. c) Computed effective mass of electron (red triangle) and hole (black solid circle) versus the biaxial strain.
