A research team has successfully developed a new technology that converts the conductivity properties of semiconductors with just one laser process.

The research team successfully converted titanium oxide (TiO₂), which conventionally works based on electrons, into a hole-based p-type semiconductor. The Laser-Induced Oxidation and Doping Integration (LODI) technology developed by the research team can simultaneously execute oxidation and doping with just one laser irradiation, and it is noted as a novel conversion technology that can drastically streamline the traditional complex process.

The study is published in the journal Small. The team was led by Professor Hyukjun Kwon from the Department of Electrical Engineering and Computer Science, Daegu Gyeongbuk Institute of Science and Technology.
