Specifically, this research will entail coating nano-sized BaTiO3 particles with appropriate coatings to produce n-doped and p-doped semiconductors. The samples will be prepared using a Direct Current Sintering (DCS) furnace which will allow production of thermoelectric materials which have nano-sized grains. The goal is to increase the ZT value above 0.5 in this study. To decrease thermal conductivity, nano-sized powders will be micro-milled to approximately 30 nm before coating with 5-10 nm layer. Sintering in the DCS furnace will be done to ensure that grain growth does not occur.","destinations":[{"lkuCodeId":1543,"code":"EARTH","description":"Earth","lkuCodeTypeId":526,"lkuCodeType":{"codeType":"DESTINATION_TYPE","description":"Destination Type"}}],"startYear":2015,"startMonth":10,"endYear":2016,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":506296,"canUserEdit":false,"firstName":"Dennis","lastName":"Tucker","fullName":"Dennis S Tucker","fullNameInverted":"Tucker, Dennis S","middleInitial":"S","primaryEmail":"dr.dennis.tucker@nasa.gov","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":335305,"canUserEdit":false,"firstName":"Michael","lastName":"Lapointe","fullName":"Michael R Lapointe","fullNameInverted":"Lapointe, Michael R","middleInitial":"R","primaryEmail":"michael.r.lapointe@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":392233,"canUserEdit":false,"firstName":"Richard","lastName":"Howard","fullName":"Richard W Howard","fullNameInverted":"Howard, Richard W","middleInitial":"W","primaryEmail":"richard.w.howard@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":28,"canUserEdit":false,"firstName":"John","lastName":"Dankanich","fullName":"John W Dankanich","fullNameInverted":"Dankanich, John W","middleInitial":"W","primaryEmail":"john.dankanich@nasa.gov","publicEmail":true,"nacontact":false}],"website":"https://www.nasa.gov/directorates/spacetech/home/index.html","libraryItems":[],"transitions":[{"transitionId":53796,"projectId":91682,"transitionDate":"2016-09-01","path":"Closed Out","infoText":"Closed out","infoTextExtra":"","dateText":"September 2016"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"MSFC CIF","active":true,"description":"Through the Center Innovation Fund, the Space Technology Mission Directorate allocates a small portion of the NASA workforce and procurement budget to internal research and development to feed early stage innovation in technology and exploration.
