The project focuses on nitride vertical devices with inverted built-in polarization fields in structures grown on Ga-polar GaN substrates. To build such devices we will exploit unique features of n-p tunnel junctions (TJ). Growth of n-p TJ preceding the active region of the device allows to incorporate the active region within the p-n configuration rather than the commonly used n-p one. This results in an inverted built-in electric field direction inside the active region. Additionally, such devices will profit from having the n-type layer on the top. We will show that both features can lead to new applications of light emitting devices, laser diodes and transistors. Unique capabilities of the plasma-assisted molecular beam epitaxy system (high growth rate nitrogen plasma source, high Mg flux cell and Ge doping) installed in Warsaw will be crucial for samples growth. Project will be carried out in collaboration with groups at Cornell University and Wroclaw University of Technology. (Polish)
