Summary of Jianwu Sun's activities


Jianwu Sun received his Docent (Associate Professor) title in 2016 and now he holds a permanent position at Linköping University. His research interest focuses on exploring the semiconductor materials for solar-driven energy conversion, in particular, photocatalytic and photoelectrochemical (PEC) water splitting and reduction of CO2.

The solar-driven water splitting provides a promising way to produce hydrogen, which is regarded as a renewable and environment-friendly energy source because of its high energy density (three times that of gasoline) and clean by-product (water) when used for energy generation. Hydrogen driven cars have been available in market. Moreover, the solar driven conversion of CO2 and water into chemical fuels is also a very attractive approach to explore renewable energy by consuming and recycling the greenhouse gas CO2.

Now Jianwu Sun has been granted on the research of exploring cubic silicon carbide (3C-SiC) as a photoelectrode for the PEC water splitting and CO2 reduction. Compared to commonly studied photoelectrode materials, the 3C-SiC has outstanding properties such as suitable bandgap (2.36 eV) for efficient visible light absorption and proper energetics for water splitting without applying external bias.



Jianwu Sun, was recetly recruited from the world-leading industrial research institution: IMEC, Belgium. He has more than ten-year academic and industrial research experience on MBE, MOCVD, CVD, and sublimation growth of semiconductors SiC, ZnO, GaN, Ge and SiGe as well as optical and electrical characterizations of semiconductors. He has more than 40 published papers and one industrial Patent (First inventor, IMEC, Belgium).

Jianwu Sun got his Ph. D degree in 2008. His PhD work was focusing on MBE growth of p-type ZnO, ZnMgO/ZnO quantum wells, and the fabrication of ZnO-based LEDs. From 2008 to 2010, he was working on InGaN solar cells as an Assistant Professor in Xiamen University, China. From 2009 to 2013, he did postdoctoral research on SiC in CNRS-Université Montpellier II, France and Linköping University, respectively. From 2013 to 2014, he was permanently employed as Senior Researcher in IMEC, Belgium and worked on the CVD-growth of Ge/SiGe for the development of the CMOS beyond 10 nm node technology. From 2015 to now, he holds a permanent position at Linköping University.
