Two-dimensional (2D) materials have been attracting attention since graphene monolayer was firstly separated. However, after an explosive boom, there is always quandary and stagnancy following and soon will come the refractory period of capital market. To avoid that undesired future, a paradigm of quasi 2D monolayer has been contemplated and devised in this article, with examples studied theoretically. The results show the general dynamic nonlinearity, and the expected tunability of bandgap without extra doping or substitution. These together suggest its intriguing both electronical and mechanical properties, which will enrich the arsenal of potential 2D materials.
