S. I. Mitryukovskiy, A. A. Nikulin, A. I. Stognij, and T. V. Murzina<br/> Optical second-harmonic (SH) generation in planar Au/Co/Si(111) nanostructures under application of static magnetic and electric fields is studied experimentally. The crystallographic, magneto- and electroinduced contributions to the SH intensity reveal strong azimuthal...

Hyung Keun Yoo, Sun-Goo Lee, Chul Kang, Chul-Sik Kee, and Joong Wook Lee<br/> The characteristics of terahertz (THz) modulation in organic copper phthalocyanine thin films deposited on a Si wafer were investigated by angle-dependent photoexcitation. We reveal that the efficiency of THz modulation reflects not only the angle-dependent reflectivity...

Chun Wang I. Chan, Qing Hu, and John L. Reno<br/> A terahertz quantum cascade laser is presented in which selectively placed pure AlAs barriers are used to reduce parasitic leakage currents to the conduction band continuum. The design is demonstrated to have improved temperature performance over a regrowth of the current T ~ 200 K record holder...

Xiuguo Chen, Chuanwei Zhang, and Shiyuan Liu<br/> Mueller matrix polarimetry (MMP) is introduced to characterize nanoimprinted grating structures, and noticeable depolarization effects from measured data are observed. We demonstrate that these depolarization effects are mainly induced by the finite bandwidth and numerical aperture of the instrument...

Ernest Y. Wu, Baozhen Li, and James H. Stathis<br/> We report a time-dependent clustering model for non-uniform dielectric breakdown. Its area scaling and low-percentile scaling properties are rigorously investigated. While at high percentiles non-uniform area scaling dominates, the model restores the weakest-link characteristics at low percentiles...

Lynn B. Munday, Robert L. Mitchell, Jaroslaw Knap, and Peter W. Chung<br/> We show that a molecule's flexibility described by changes to its conformation and orientation during deformation is vital for the proper representation of dislocation nucleation in molecular crystals. This is shown for the molecular crystal hexahydro-1,3,5-trinitro-s-triazine...
