LED streetlights are to illuminate the dark in a most crime-ridden block in the city of San Francisco. And the Mayor Gavin Newsom will visit the section today to test the energy-saving light source by lighting four street lights using his iPhone.
LED street lights consume much less power than traditional streetlights. And the lights with computer chips are networked over power lines thus can be shut off when no one is around. Besides, LED lights require far less maintenance and are tough to break. But these are not the most important for this weirdest section in the city.

Group III-nitride materials have been widely used for visible and ultraviolet LEDs and blue, violet laser diodes in the past decade. Most of these optoelectronic devices are typically fabricated on the conventional polar (0001) c-plane oriented substrate materials. Devices grown on the polar substrate orientation suffer undesirable spontaneous and piezoelectric polarization resulting in significant band bending in the quantum well. This reduces radiative recombination efficiency and lowers device performance.
