U.S. Drops Charges That Professor Shared Technology With China
When the Justice Department arrested the chairman of Temple University’s physics department this spring and accused him of sharing sensitive American-made technology with China, prosecutors had what seemed like a damning piece of evidence: schematics of sophisticated laboratory equipment sent by the professor, Xi Xiaoxing, to scientists in China.
The schematics, prosecutors said, revealed the design of a device known as a pocket heater. The equipment is used in semiconductor research, and Dr. Xi had signed an agreement promising to keep its design a secret.
But months later, long after federal agents had led Dr. Xi away in handcuffs, independent experts discovered something wrong with the evidence at the heart of the Justice Department’s case: The blueprints were not for a pocket heater.
.. “If he was Canadian-American or French-American, or he was from the U.K., would this have ever even got on the government’s radar? I don’t think so,” Mr. Zeidenberg said.
.. About a dozen F.B.I. agents, some with guns drawn, stormed Dr. Xi’s home in the Philadelphia suburbs in May, searching his house just after dawn, he said. His two daughters and his wife watched the agents take him away in handcuffs on fraud charges.
.. Temple University put him on administrative leave and took away his title as chairman of the physics department. He was given strict rules about who at the school he could talk to. He said that made it impossible for him to continue working on a long-running research project that was nearing completion.
