This Review highlights basic and transition metal conducting and semiconducting oxides.
We discuss their material and electronic properties with an emphasis on the crystal …

High-temperature materials including oxides, borides, carbides, and nitrides encompass all
types of conductors: metallic, semiconducting, and ionic. Their electrical conductivities are …

We show that flash-sintering in MgO-doped alumina is accompanied by a sharp increase in
electrical conductivity. Experiments that measure conductivity in fully dense specimens …

Nearly pure α-alumina samples produced by uniaxial pressing were flash sintered under
electrical fields ranging from 500 V/cm to 1500 V/cm in experiments at constant heating rate …

We report a theoretical survey of defect energetics in α-Al 2 O 3 and rutile Ti O 2 which we
relate to structural and transport properties of these materials. The study of these crystals …

Abstract The undoped, Mg 2+ doped, Ce 3+ doped as well as Mg 2+: Ce 3+ codoped Gd 3
Al 2 Ga 3 O 12 crystals were grown from the melt by the micro-pulling down method. Ce 3+ …

This book proposes a wide overview of the research and development of proton-conducting
solid oxide materials. It is the first to approach the topic on proton-conducting ceramics and …

We start this discourse with a short historical discussion of corundum heat treatment and the
connection of this new treatment to previous processes. That is followed by a summary of …

The dc conductivity and ionic transference number of MgO single crystals doped with Al, Fe,
and Sc were measured as a function of temperature (1200° to 1600° C) and oxygen …

Towards combating climate change, the widespread replacement of fossil fuel energy with
zero-carbon energy has two main requirements:(1) the ability to reach very high …
