In 2004 he became a Fellow at the Institute of Physics, UK (FinstP), at the American Physical Society (APS, Materials Physics) in 2009 and in 2020 he became a Fellow International at the Japanese Society for Applied Physics (JSAP). He became a member of the Royal Physiographic Society in 1998, of KVA, the Royal Swedish Academy of Sciences (Physics Class) in 2006 and of IVA, the Royal Swedish Academy of Engineering Sciences in 2007. In 2008, he was named "Einstein Professor" by the Chinese Academy of Sciences. In 2013, he was awarded the IUVSTA Prize for Science for Triennium 2010-2013 and in 2014 the Fred Kavli Distinguished Lectureship in Nanoscience. In 2018, he was awarded the Wilhelm Westrup Prize for basic materials science leading to the creation of commercial value.
