A Japanese scientist who created an iron layered semiconductor stabilized with phosphorous discovered that the material had zero resistance at minus 269º Celsius.

According to nikkei.net, Yoichi Kamihara, who works at the Tokyo Institute of Technology, has spurred interest in high temperature superconductors in scientists' search for superconductors which exhibit these characteristics at room temperature.

He has worked to produce iron based superconductors replacing phosphorous with other elements including arsenic, and is now creating quality samples for further research.

His discoveries have caused scientists in Japan, China, the USA and Europe to race towards the winning post - a superconductor at room temperature, said the article, here. X
