Charge transport magnetic materials

Wasielewski s research interests comprise photoinduced electron transfer and charge transport in organic molecules and materials, artificial and natural photosynthesis, self-assembly of nanoscale materials, spin dynamics of multispin organic molecules, materials for molecule-based optoelectronics and spintronics, and time-resolved optical and magnetic resonance spectroscopy. His research has resulted in over 300 publications. Dr. Wasielewski was elected a fellow of the American Association for the Advancement of Science in 1995, and has held numerous distinguished lectureships and fellowships. Among Wasielewski s recent awards are the 2004 Photochemistry Research Award of the Inter-American Photochemical Society and the 2006 James Flack Norris Award in Physical Organic Chemistry of the American Chemical Society. 

The effective mass is a term used in solid-state physics describing the properties of an electron in the presence of an electric or magnetic field, in the conduction band (or hole in the valence band) of a semiconductor crystal. It has different values in different materials and is used in charge transport calcnlations or to calculate the density of states. The value is usually smaller than the real electron mass, mo = 9.11 x 10 kg or 0.511 MeV. For a more detailed description see Memming and Brus. ... 

Many of these studies were designed to understand the charge transport process, " because the structure of these materials is much more complex than that of traditional crystalline and glassy solids. Berthier et al used nuclear magnetic resonance (NMR) to demonstrate that ionic conductivity...
