99-percent of the light through it. Tech-On also covered the actual structure of the disk, reporting that an inorganic Si-Cu alloy is used for the L0 layer; the L1 to L9 layers consist of bismuth peroxide and germanium dioxide. With a disk composing of numerous...

growing". Pamela’s team recently added a research effort in CMOS (Complementary Metal Oxide Semiconductor). They also continue active development into several areas of SOI (Silicon On Insulator), bulk silicon and SiGe (Silicon Germanium) research, as well...

DoE and NASA have been approaching 40%. A new material now allowed the NREL to increase the efficiency by a few more percentage points. Instead of using a germanium wafer as the bottom junction of the device, the new design uses compositions of gallium indium...
