As an approximation to the quantum state of solids, the band theory, developed nearly seven decades ago, fostered the advance of modern integrated solid-state electronics, one of the most successful technologies in the history of human civilization. Nonetheless, their rapidly growing energy consumption and accompanied environmental issues call for more energy-efficient electronics and optoelectronics, which necessitates the exploration of more advanced quantum mechanical effects, such as band-to-band tunneling, spin-orbit-coupling, spin-valley locking, and quantum entanglement. The emerging two-dimensional (2D)-layered materials, featured by their exotic electrical and structural properties, provide a revolutionary low-dimensional and manufacture-friendly platform (and many more opportunities) to implement these quantum engineered devices, compared to the traditional electronic materials system. In this perspective article, we review the progress and analyze the opportunities/challenges of exploiting 2D-materials to highlight their unique quantum properties that enable novel energy-efficient devices, and provide our insight to quantum device engineers and 2D-material scientists.
