摘要
石墨烯玻璃是指表面生长有石墨烯的玻璃,它将石墨烯与玻璃的优异特性结合起来,具有良好的透明性、导电性、导热性和表面疏水性等特点~([1,2])。由于玻璃是一种成本低廉,应用广泛的传统材料,因此石墨烯玻璃有望像玻璃一样走进日常生活,成为一种应用广泛、性能优异的新型材料。高品质石墨烯玻璃的制备通常需要较高的温度和较长的时间~([1]),这是实现石墨烯玻璃广泛应用需要解决的主要挑战之一。本研究提出"气流限域化学气相沉积法",即通过在玻璃衬底(石英玻璃、蓝宝石玻璃、硼硅玻璃等耐高温玻璃)表面覆盖磨砂石英片,由于反应气体在流经玻璃与磨砂石英片狭缝的过程中其气流受到限制,碳源裂解更充分,碳碎片与玻璃衬底之间以及碳碎片之间的碰撞频率大大增加,从而使得石墨烯在玻璃表面的生长速率和均匀性明显提升。在相同生长参数下,采用气流限域化学气相沉积方法得到的石墨烯玻璃在品质上要显著优于传统方法得到的石墨烯玻璃。在此基础上,我们展示了该方法制得的石墨烯玻璃可作为透明加热器件用于除雾,并且可作为衬底用于高品质氮化铝薄膜的外延生长。
Graphene glass integrates the fascinating properties of pristine graphene and widely-used glasses, offering great potentials for practical applications of graphene in our daily life[1,2]. One of the technical hurdles toward the wide applications of graphene glass is the slow growth kinetics of graphene on glasses in the CVD process[1]. We report herein a confined-flow CVD approach by creating a 2-4 ?m wide gap above the glass substrate with plenty of stumbling blocks for the high-efficiency fabrication of graphene glass. As a result, the growth rate of graphene glass was remarkably increased together with an improvement of growth quality and uniformity as compared to the conventional gas flow CVD technique. Thus-obtained high quality graphene glasses exhibited an excellent defogging performance and the graphene sapphire glass was found to be an ideal substrate for growing uniform and ultra-smooth aluminum nitride(Al N) thin films without the tedious pre-deposition process of a buffer layer.
