Growth and optical properties of CaxCoO2 thin films

Engineering Faceted Nanoporosity by Reactions in Thin-Film Oxide Multilayers in Crystallographically Layered Calcium Cobaltate for Thermoelectrics

“…The thickness of the films was determined from cross-sectional TEM images. As in our earlier work, 55 the Seebeck coefficient α was measured in a home-built thermoelectric measurement setup equipped with two Peltier heat sources and two K-type thermocouples. Two Cu metal electrodes (1.5 cm × 4 cm) contact with hot and cold plates and the thermocouples (diameter 0.1 mm) were wrapped in the Cu electrodes separated by insulation tape.…”

Epitaxial Growth of CaMnO3–y Films on LaAlO3(112¯0) by Pulsed Direct Current Reactive Magnetron Sputtering

“…The Seebeck coefficient α was measured in a home‐built setup, previously described, [ 13 ] equipped with two Peltier heat sources and two 0.1 mm‐diameter K‐type thermocouples, for creating a temperature gradient and for measuring the temperature, respectively. Two, 1.5 × 4 cm 2 in size, Cu electrodes were attached to, but electrically isolated from, the thermocouples, in contact with the hot and cold spots, and connected to a Keithley 2001 multimeter.…”

“…Further, the existing thermoelectric energy conversion devices/generators are usually manufactured from toxic and expensive semiconductors such as bismuth tellurides, led tellurides, and their alloys [26] , [27] , [28] . Therefore, the current thermoelectric research is focused on finding low-cost and non-toxic thermoelectric conductors for the application [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] . With some improvements and modifications in the thermoelectric properties of graphite such as by organic doping or alloying with other semiconductors, they can also be utilized in the fabrication of thermoelectric devices [19] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] .…”
