Biography

Grandjean was born in Dijon, France, and is a French and Swiss citizen. He studied at the University of Clermont-Ferrand and the Université Nice-Sophia-Antipolis. In 1991, he joined the Solid-State Physics and Solar Energy Laboratory, a division of the French National Center for Scientific Research where he studied semiconductor nanostructures. By 1994 he obtained his Ph.D. and became a CNRS winner. Later on, as a senior research fellow, he worked at the Research Center for Heteroepitaxy and its Applications, a division of CNRS in Sophia Antipolis. In 2004, he became a tenure-track professor at the École Polytechnique Fédérale de Lausanne becoming a director of the Laboratory of Advanced Semiconductors for Photonics and Electronics where he still serves. He was promoted Full Professor in 2010. From 2012 to 2016, he was the director of the Institute of Condensed Matter. Since 2019, he is a board member of Riber, a world's leading supplier of Molecular Beam Epitaxy (MBE) products.

Research

In 1999, he along with his colleagues, have discovered that combining gallium nitride (GaN) and quantum dots (QDs) into aluminum nitride (AIN) matrix, produces a glowing white light. In 2006, his group and colleagues at the University of Southampton reported polariton lasing at room-temperature.
