      abstract     = {Within the last years, III-nitride-based devices have been
                      demonstrated with exceptional performance. There is,
                      however, a severe lack of knowledge when it comes
                      fabrication of p-channel devices. p-Channel heterostructure
                      field-effect transistors (HFETs) could open the way for
                      nitride-based complementary logic. Here, a comprehensive
                      study of enhancement and depletion mode p-channel
                      GaN/AlInGaN HFETs is performed. The influence of a highly
                      p-doped GaN cap layer on device performance is investigated.
                      Gate recessing and changes in composition of the backbarrier
                      are analyzed. ON/OFF ratios of up to 108 and subthreshold
                      swings of about 75 mV/decade are achieved.},
