Characterization of Bi4Ge3O12 single crystal by impedance spectroscopy

Materials Research, 2003
Bi4Ge3O12 (bismuth germanate - BGO) single crystals were produced by the Czochralski technique and their electrical and dielectric properties were investigated by impedance spectroscopy. The isothermal ac measurements were performed for temperatures from

p-Type Quasi-Mono Silicon Solar Cell Fabricated by Ion Implantation

International Journal of Photoenergy, 2013
The p-type quasi-mono wafer is a novel type of silicon material that is processed using a seed directional solidification technique. This material is a promising alternative to traditional high-cost Czochralski (CZ) and float-zone (FZ) material. Here, we
