$\mu$-$\tau$ Permutation Symmetry and Neutrino Mixing for Two-loop Radiative Mechanism
Ichiro Aizawa,Masaki Yasue,Motoyasu Ishiguro,Teruyuki Kitabayashi 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.3
Neutrino oscillations characterized by large mixing angles and very tiny masses less than O(0.1) eV are explained by using a two-loop radiative mechanism to generate neutrino masses and by the presence of a - permutation symmetry. This scenario is realized in a specic model based on SU(3)L U(1)N, where the ordinary lepton doublets in SU(2)L U(1)Y are extended into lepton triplets in SU(3)L U(1)N. The third members of the lepton triplets play the crucial role of explaining the almost maximal mixing in the atmospheric neutrino oscillation.

We have compared the electrical performance of a proposed normally-off GaN-based MIS-HEMTs employing ultrathin AlGaN barrier layer in the channel with those of conventional recessed-gate structure MIS-HEMTs. The proposed device exhibited much less density of interface states extracted from the measured capacitance-voltage characteristics, suggesting improved Al2O3/AlGaN interface. For corresponding three-terminal transistors, while the conventional reference device exhibited poor control of gate-to-source voltage on drain current with about 3 V hysteresis in the transfer curves, the proposed device showed well-behaved subthreshold characteristics with only 0.8 V hysteresis. Furthermore, the proposed device showed a much higher VTH of +5 V compared to +1 V of the conventional reference device.
