Abstract
A method for controllable layer-by-layer removal of graphene layers is provided. The method includes the steps of: disposing a single-layer or multi-layer graphene on a heat source, arranging graphene layer or layers in a sealed chamber filled with ozone gas, and removing a targeted area of graphene with a laser. The method provides low-temperature removal of graphene layer-by-layer. The heat source, laser, and the highly oxidizing ozone gas selectively control the removal of graphene layers.
