      abstract     = {The built-in piezoelectric fields in group III-nitrides can
                      act as road blocks on the way to maximizing the efficiency
                      of opto-electronic devices. In order to overcome this
                      limitation, a proper characterization of these fields is
                      necessary. In this work nano-beam electron diffraction in
                      scanning transmission electron microscopy mode has been used
                      to simultaneously measure the strain state and the induced
                      piezoelectric fields in a GaN/AlN multiple quantum well
                      system.},
