In　present　paper,　by　using　the　nonequilibrium-Greenfunction　approach,　we　investigated　the　thermopower　through　a　quantum　dot　connected　to　Luttinger　liquid.　The　generally　analytic　thermopower　formula　for　the　thermopower　is　firstly　derived　to　take　into　account　intralead　electron　interaction.　The　thermopower　S　varies　linearly　with　the　temperature　T　at　low　temperature　and　is　enhanced　by　intralead　electron　interaction.　These　features　qualitatively　agree　with　the　experimental　and　theoretical　results.　©　2011　IEEE.
