研究概况

目前科研攻关方向:

1、基于衍射神经网络算法的光电人工智能计算芯片研究

2、基于神经拟态器件的感存算一体化芯片设计与验证

已有成果:

1、提出并实验验证了一种基于忆阻器智能淬火原理的高速单光子雪崩探测器。比传统半导体单光子雪崩探测器具有更高计数速率,更集成的优点。同时,实验发现单光子雪崩信号可以调制淬灭电阻的阻值,从而制作光电子神经拟态学器件。

2、从第一性原理计算出发,提出了Minigap理论,成功解释了基于AlInAs和AlInAsSb数字合金材料的线性雪崩探测器具有极低噪声的原因。

3、提出并验证了基于AlN/GaN周期性异质结材料的高增益线性雪崩探测器,可以在简单伺服驱动模式下工作并具有超高灵敏度。

以第一作者在Journal of Lightwave Technology,Applied physics Letters,Journal of applied physics等期刊上发表SCI论文11篇。第一作者Journal of Lightwave Technology论文被当做那一期杂志的封面论文。受邀参加国际会议IEEE Photonics Conference和SPIE Defense+Commercial Sensing做邀请报告。第一作者Applied Physics Letters论文被Compound Semiconductor杂志以封面工作进行报道(该杂志首次封面报道中国学者工作),被Semiconductor Today以Headline News形式进行报道。申报人拥有已授权专利3项,2项在审专利,包含一项美国专利;担任Journal of Lightwave technology, Journal of Journal of Selected Topics in Quantum Electronics,IEEE electron Device Letters等国际一流期刊审稿人。先后7次在海外大学、国家实验室或国际学术会议(如弗吉尼亚大学、芝加哥大学、阿贡国家实验室,SPIE Photonics West)做特邀报告或者口头报告;海外博后工作阶段参与美国国防高级研究局(DARPA),美国陆军实验室(ARL),海军实验室(ONR)等机构基础研究项目,博士阶段参与中国自然科学基金面上项目等科研项目。
