We report a study of the 2.8 eV blue luminescence (BL) in heaviliy Mg-doped p-GaN via resonant excitation with a tunable blue dye laser. The dependence of the BL on the excitation photon energy (Eex) is unlike that of the yellow luminescence found in n-type GaN. An Urbach-type band tail, with Urbach parameter of 33 meV is observed in the vicinity of the BL energy. We propose that the peak energy of the BL marks the transition from localized states to delocalized states within this band tail.

“Most energy conservation information is designed for homeowners, even though an increasing number of people are renting,” says Leona K. Hawks, Utah State University Extension housing specialist. “Many renters develop a short-timer mentality and don’t worry much about energy savings. However, utility bills do add up quickly so renters may wish to conserve on their energy use,” she advises.

“With the price of fuel skyrocketing, now is the time to think about energy-saving projects around the house, and the best place to start is with your windows,” advises Leona K. Hawks, Utah State University Extension housing specialist.

The University of Wollongong (UoW) has received funding for the research and development of a 20 kJ high temperature superconducting magnetic energy storage device (HTS SMES). This SMES will be operated at 25 K in contrast to most existing HTS designs, which operate at 77K. This paper includes a literature review of the current technology for the configuration of the SMES coil and a summary of the work done at UoW to date. Solenoidal and toroidal coils designs are compared to determine which will provide the required level of energy stored for a minimum superconductor and device volume. The design …
