      abstract     = {Different from the two-dimensional (2D) topological
                      insulator, the 2D topological crystalline insulator (TCI)
                      phase disappears when the mirror symmetry is broken, e.g.,
                      upon placing on a substrate. Here, based on a new family of
                      2D TCIs—SnTe and PbTe monolayers—we theoretically
                      predict the realization of the quantum anomalous Hall effect
                      with a Chern number C=2 even when the mirror symmetry is
                      broken. Remarkably, we also demonstrate that the considered
                      materials retain their large-gap topological properties in
                      quantum well structures obtained by sandwiching the
                      monolayers between NaCl layers. Our results demonstrate that
                      the TCIs can serve as a seed for observing robust
                      topologically nontrivial phases.},
