| Research Abstract |
We have made search to obtain novel materials which have electron conduction in majority spin band and hole conduction in minority band, which offer a novel method for achieving effective spin current generation by temperature gradient, based on first principle electronic structure calculation. Our theoretical studies suggest that Mn, Fe and Co doped GaMnAs and Mn-doped InAs/GaSb superlattices are the good candidates for the purpose. However, experimental evidence has not been obtained yet.
