The average values of electrical conductivity, thermal conductivity, Seebeck coefficient, figure of merit (ZT) and the average value of the power factor (Pav) are reported and discussed in detail. While pristine graphene is a zero band gap semiconductor, adsorption of H2S onto the bridge site opens up a direct energy gap of about 0.04 eV, adsorption of a H2S molecule onto the top site opens up a gap of 0.3 eV, and adsorption of H2S onto the hollow site makes it metallic. The investigation of ZT and power factor values suggests that a top-site configuration could be a potential candidate for thermoelectric applications in the range 300-600 K. 2015-03-24T04:20:39Z 2015-03-24T04:20:39Z 2014-04 Book Journal of Materials Chemistry C, vol.2(13), 2014, pages 2346-2352 2050-7534 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/39295 http://pubs.rsc.org/en/Content/ArticleLanding/2014/TC/c3tc32260b en Royal Society of Chemistry |
