Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

open access: yesAdvanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Predicted Effect of Projectile Dispersion on Target Hit Probabilities and Dispersion-Zone Sizes for the 25-mm Gun of the Bradley Fighting Vehicle

open access: closed, 1988
Abstract : This research note presents the mathematical analysis used to predict the effect of varied levels of projectile dispersion on a) dispersion-zone size, and b) hit probabilities for targets engaged with the 25-MM gun of the Bradley Fighting Vehicle.
