摘要

Recent studies in van der Waals coupled two-dimensional (2D) bilayer materials have demonstrated a new freedom for material engineering by the formation of moiré pattern.By tuning the twist angle between two layers,one can modulate their electronic band structures and therefore the associated electrical transport and optical properties,which are distinct from the original ones of each individual layer.These new properties excite great passion in the exploration of new quantum states and possible applications of 2D bilayers.In this article,we will mainly review the prevailing fabrication methods and emerging physical properties of twisted bilayer materials and lastly give out a perspective of this topic.
