Two-dimensional (2D) charge density wave (CDW) materials have attracted widespread attention due to their exotic physical properties. Compared to their bulk forms, 2D CDW materials exhibit many excellent features, offering new possibilities for electronic device applications. In this Perspective we highlight the unique advantages of 2D CDW materials and identify some key challenges which remain to be addressed.

Schematic of the unique advantages of 2D CDW materials for electronic device applications. Compared to their bulk forms, 2D CDW materials can exhibit higher phase transition temperatures and more exotic electronic properties such as Mott insulators and topological insulators. They can also be easily modulated by various methods such as strain and doping[30,32,37].
