13Optimized Mn and Bi co-doping in SnTe based thermoelectric material:A case of band engineering and density of states tuning显示文摘Tin telluride(SnTe)overwhelmingly continues to be studied owing to its promising thermoelectric properties,tunable electronic structure,and its potential as an alternate to toxic lead telluride(PbTe)based materials.In this research,we engineer the electronic properties of SnTe by co-doping Mn and Bi below their individual solubility limit.The First principles density functio nal theory studies reveal that both Bi and Mn introduce resonance states,thereby increasing the density of states near the Fermi level leading to enhanced Seebeck coefficient.This unique combination of using two resonant dopants to introduce flatter bands is effective in achieving higher performance at lower tempe ratures manifesting into a large Seebeck value of~91μV/K at room temperature in the present case.Both elements optimally co-doped results in a very high power factor value of~24.3μW/cmK^(2) at 773 K when compared to other high performance SnTe based materials.A zT of~0.93 at 773 K is achieved by tuning the proportion of the co-dopants Mn and Bi in SnTe.The hardness value of pristine SnTe was also seen to increase after doping.As a result,synergistic optimized doping proves to be a suitable means for obtaining thermoelectric materials of superior characteristics without the need for heavy doping.Samuel Kimani Kihoi Joseph Ngugi Kahiu Hyunji Kim U.Sandhya Shenoy D.Krishna Bhat Seonghoon Yi Ho Seong Lee 2021Journal of Materials Science & Technology2021,,26:1
14Enhanced thermoelectric composite performance from mesoporous carbon additives in a commercial Bi_(0.5)Sb_(1.5)Te_(3) matrix显示文摘Composites were prepared,through hot pressing,using carbon materials with different pore size distributions as additives for commercial Bi_(0.5)Sb_(1.5)Te_(3) thermoelectric material(BST,p-type).Thermoelectric properties of the composites were measured in a temperature range of 298-473 K.Thermal conductivity of the composites,especially lattice thermal conductivity,was effectively decreased due to the mesoporous properties of the incorporated carbon additives.The electrical conductivity of the composites slightly decreased due to the electron scattering at the interface between the carbon material and the commercial BST matrix.The composite with 0.2 vol.%mesoporous carbon powder(36%mesoporosity)exhibited a figure of merit value approximately 10.7%higher than that of commercial BST without additives.This behavior resulted in 116%improved output power in the composite block-based single element compared with a bare BST thermoelectric block.The enhanced figure of merit was attributed to the effective reduction of lattice thermal conductivity by acoustic phonons scattering at the interface between the BST matrix and the mesoporous carbon as well as at the pore surfaces within the mesoporous carbon.By utilizing mesoporous carbon materials used in this study,the shortcomings and economic difficulties of the composite process with low dimensional carbon additives(carbon nanotubes,graphene,and nanodiamond)can be overcome for extensive practical applications.Mesoporous carbon powder with a tailored porosity distribution revealed the validity of bulk-type carbon additives to enhance the figure of merit of commercial thermoelectric materials.Seong-Tae Kim Jong Min Park Kwi-Il Park Sang-Eun Chun Ho Seong Lee Pyuck-Pa Choi Seonghoon Yi 2021Journal of Materials Science & Technology2021,,35:0
