目前主要从事纳米非晶固体材料（Nanoglass）的研究。Nanoglass是世界公认的纳米晶材料创始人H.Gleiter教授提出纳米结构材料的一个全新概念，其本质是引入大量纳米级界面的非晶固体材料，其特点是通过控制引入界面的密度以及界面自由体积的扩散程度，材料整体的原子结构和密度（以及所有与原子结构和密度相关的性能）可以得到有效的调控。Nanoglass的研究为打开了固体材料原子结构和性能调控的大门提供了一把钥匙。

冯涛教授长期从事纳米材料领域的研究，研究工作主要可分为两部分：2010年前主要从事纳米碳材料及其场致电子发射的研究，2010年作为洪堡学者赴德以后主要从事纳米玻璃材料的研究。在国内最早开展了采用印刷法制备碳纳米管场发射平板显示器（CNT-FED）的研究工作，并提出了采用等离子体表面处理技术提高CNT发射性能的方法，为大面积、低成本地制备CNT阴极打下了基础。在国内最早采用全印刷工艺实现了三极管结构器件的制备，使真正低成本制备CNT-FED器件成为可能。2008年其领导的研究小组成功开发了可动态显示的40英寸CNT-FED显示屏，目前仍是国内报导的最大尺寸的FED显示屏。2007年获上海市青年科技启明星称号；2008年获上海市创新人才称号；2010年获上海市科技进步奖三等奖（排名第五）；同年获“洪堡学者”称号。作为项目负责人完成了国家自然科学基金项目“离子束辅助沉积Pt/C混合膜的制备及抑制栅电子发射机理研究”，上海科委纳米专项项目“可驱动纳米碳显示器的研制”，“高效节能冷光源及大屏幕显示模块的研制及产业化”，“新型低成本CIGS薄膜太阳能电池研究”，上海市科技启明星项目“超大屏幕用纳米碳管显示模块的关键技术研究”，和上海市人才发展基金项目“40英寸纳米碳管显示屏开发的关键技术研究”。已在Appl. Phys. Lett.，Nanotechnology 等国内外学术期刊和学术会议上发表论文50余篇；在显示领域国际顶尖会议Asia Display上连续两年（07,08）做大会邀请报告（唯一一位连续两年做邀请报告的来自中国大陆的学者）；同时申请了发明专利10余项，获得专利授权2项。近期发表的论文有：
