CuNdO2,　a　p-type　transparent　conducting　oxide　has　been　synthesized　by　conventional　solid-state　reaction.　The　XRD　and　TEM　results　show　that　the　pure　delafossite　phase　is　obtained,　furthermore,　the　EDX　results　indicate　the　sample　is　obviously　oxygen-rich.　The　p-type　conduction　of　CuNdO2　was　confirmed　by　Hall　and　Seebeck　measurements.　Carrier　concentration　and　mobility　at　room　temperature　are　around　1.38　x　10(17)　cm(-3)　and　1.24　cm(2)V(-1)s(-1),　respectively.　On　the　other　hand,　the　optical　band　gap　of　CuNdO2　is　estimated　to　be　around　3.14　eV,　which　agrees　well　with　the　theoretical　result　predicted　by　the　first-principle　calculation.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
