Electron traps in rutile [PDF]
, 1986 Undoped samples of single crystal rutile and rutile powder have been studied by the methods of photoluminescence, thermoluminescence and thermally stimulated conductivity. Crystal samples doped with chromium, iron, manganese, cobalt and nickel and powder

Electrical Characterization of Intrinsic and Induced Deep Level Defects in Hexagonal SiC [PDF]
, 1996 Deep level defects in hexagonal SiC were studied using digital deep level transient spectroscopy (DLTS) methods over the temperature range of 100 to 800 deg K. New centers were found in bulk and epitaxial 6H-SiC with ionization energies between 0.38 to 1.
