Breakthrough could launch organic electronics beyond cellphone screens

November 21, 2017

An international team of researchers including Princeton (Prof. Antoine Kahn, Prof. Barry Rand, graduate students Xin Lin, Kyung Min Lee, Michael A. Fusella, and Fengyu Zhang) have used ultraviolet light to split molecules that had been added to a semiconductor. The reaction involves transferring an electron from the added molecule to the semiconductor. This process, called doping, results in a surprisingly stable structure and improves the conductivity of the semiconductor dramatically. The discovery points the way to more widespread use of an advanced technology generally known as organic electronics.  The research was published on Nov. 13 in the journal Nature Materials.  More details can be found here.

Xin Lin

Xin Lin is a PhD student at Princeton University, majoring in Electrical Engineering under the supervision of Prof. Antoine Kahn. He holds a master’s degree in Microelectronics from Peking University and two bachelor’s degrees (B.S. in mathematics & applied mathematics and B.Eng. in Electronics Science and Technology) from Xi’an Jiaotong University. Names a Wu Ta-You Scholar, he visited National Tsing Hua University in 2008. His current research focuses on the general area of chemical doping of organic semiconductors with molecular dopants, more specifically, the ultra-low doping of molecular semi-conductors and the n-type doping of organic molecular semiconductors with very low electron affinity. Xin’s wife, Jing, is a landscape designer with LEED AP BD+C accreditation. They have one chinchilla.
