THz emission spectroscopy reveals optical response of GaInN/GaN multiple quantum wells
E-Mail IMAGE: Acoustic strain waves are optically generated, propagate, and emit THz waves into free space at the surface. view more Credit: Osaka University A team of researchers at the Institute of Laser Engineering, Osaka University, in collaboration with Bielefeld University and Technical University Braunschweig in Germany, came closer to unraveling the complicated optical response of wide-bandgap semiconductor multiple quantum wells and how atomic-scale lattice vibration can generate free space terahertz emission. Their work provides a significant push towards the application...
