The School of Physical Science and Technology at Inner Mongolia University (IMU) in Hohhot, capital of North China’s Inner Mongolia autonomous region, invited Luo Junwei -- a researcher from the Institute of Semiconductors of the Chinese Academy of Sciences -- to make report on Jan 3, according to IMU officials.

Interested in the topic of integrated silicon-based light sources in silicon chips, the report attracted the participation of over 50 IMU teachers, graduates and undergraduates.

In his report, Luo Junwei explained that the realization of silicon-based luminescence is the key to the development of integrated optoelectronic technology -- an international problem that has lasted for half a century.

He also discussed theoretical and experimental work in the field of silicon-based luminescence that the research group is focusing on – involving CMOS, or Complementary Metal Oxide Semiconductors, a technology used to produce integrated circuits.

After the report, IMU teachers and students discussed with Luo the theoretical and experimental difficulties in the realization of silicon-based luminescence.
