Deep-level defect-related optical properties of undoped n-type high-resistivity GaN grown by metalorganic chemical vapor deposition (MOCVD) are investigated using photoluminescence (PL), photoconductivity (PC), and persistent photoconductivity (PPC) measurements. Quite interestingly, persistent photoconductivity was observed. Through the combination of our(More)
The cubic Fe3O4 nanoparticles with sharp horns that display the size distribution between 100 and 200 nm are utilized to substitute the magnetic sensitive medium (carbonyl iron powders, CIPs) and abrasives (CeO2/diamond) simultaneously which are widely employed in conventional magnetorheological finishing fluid. The removal rate of this novel fluid is(More)
