• First 200 mm AlN-on-Si template using ammonia-based Molecular Beam Epitaxy (MBE) (06/2020)

  SOPHIA ANTIPOLIS, France, June 15th, 2020 – EasyGaN SAS, RIBER SA and the CRHEA-CNRS Laboratory reached an important milestone with the fabrication of a first 200 mm AlN-on-Si template using NH3-MBE. Read more...

• High temperature operation of sublimated GaN nanowires (Applied physics letters – 06/2020)

  As part of an international collaboration between CRHEA and NTT (Japan), GaN nanolasers with a triangular section were produced by an original method of selective sublimation. These nanowires show laser emission well above room temperature. Read more...

• Quantitative imaging of metasurface holograms A new application of vectorial ptychography (Nature Communications - 05/2020)

  Metasurfaces are photonic components obtained by structuring surfaces at a scale smaller than the wavelength of light. By generating pixelated geometrical phase and/or polarization control properties, they could revolutionize the design of ultra-compact 3D virtual or augmented reality display systems. Read more...

• Magnesium nitride: a new semiconductor epitaxially grown (Physical Review Materials - 05/2020)

  CRHEA has succeeded in growing magnesium nitride epitaxially for the first time. Even if this material is known for more than a century and exploited as polycrystalline ceramics, it had never been obtained in its crystalline form. The access to high-quality Mg₃N₂ has enabled CRHEA to measure its fundamental physical properties: lattice parameter, linear thermal expansion coefficient and energy bandgap. Read more...
