中文摘要
正在开发这一设备,以使用电光采样技术测量具有亚皮秒分辨率的快速瞬变光电导。对高温超导氧化物的快速暂态光致电导进行了初步的研究。该设施还将允许在亚皮秒的时间域内测量导电聚合物中载流子的产生、复合和传输,并将可以测量从几千兆赫(GHz)到200 GHz以上的超导传输线特性。
英文摘要
This facility is being developed to measure fast transient photoconductivity with sub-picosecond resolution using electro- optic sampling techniques. The fast transient photoinduced conductivity of high temperature superconducting oxides will be studied initially. This facility will also permit measurements in the sub-Picosecond time domain for the study of carrier generation recombination and transport in conducting polymers, and will allow measurements of superconducting transmission line characteristics from a few gigahertz (GHz) to more than 200 GHz.
