摘要
一種逐層去除石墨烯的方法，所述方法包括：設置一單層或多層石墨烯於一熱源上、放置石墨烯以及熱源於一含有臭氧的密閉腔體內，以及利用雷射去除目標區域的石墨烯。此種去除石墨烯的方法可以在低溫的條件下，由雷射光精確控制逐層去除石墨烯。另外，還可選擇性的控制或調整所述熱源、雷射以及具有強氧化力的臭氧以去除石墨烯。
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.
