Bismuth antimony telluride nanopowders were prepared by using mechanochemical method. Three different materials; Bismuth Telluride, (Bi0.75Sb0.25)2Te 3 and (Bi0.5Sb0.5)2Te 3 were synthesized. XRD and TEM analysis was carried out to confirm the results. The particle size of the material was determined by using FESEM analysis. The two alloys of Bismuth Telluride such prepared were converted in the pellet form using vacuum hydraulic pressure and their Seebeck coefficients were determined to test the material suitability for its use as a thermoelectric device. Their power factor measurement and Hall effect measurements were carried out at room temperature. Keywords: Bismuth telluride; Mechanochemical method; energy in one form into another. Use of TE solid materials Applications Nanoparticals; Seebeck coefficients in heat pump and refrigeration is well known [14] and it is now expanded such as cooled seats in luxury automobiles [15]. -

University of Tsukuba at a Glance
Maps and Data University of Tsukuba At a Glance 2019 Academic Year (Apr. 1 - Mar. 31) 1 HISTORY & CREST & SLOGAN ■ History Since its inception in Tsukuba Science City in 1973, the University of Tsukuba has offered a comprehensive curriculum of education, covering everything from literature and science to fine arts and physical education. Although the university’s roots stretch back much further than 40 years; its origins lie in the Normal School, the first of its kind in Japan, established in 1872 on the former site of Shoheizaka Gakumonjo. The school was renamed several times over the years, eventually becoming Tokyo Higher Normal School before incorporating four institutions—Tokyo Higher Normal School, Tokyo University of Literature and Science, Tokyo College of Physical Education, and Tokyo College of Agricultural Education—in 1949 to become the Tokyo University of Education, the forerunner to today’s University of Tsukuba. ■ Crest The University of Tsukuba’s “five-and-three paulownia” crest derives from the emblem adopted by Tokyo Higher Normal School students in 1903 for their school badge, which was inherited by the Tokyo University of Education in 1949. Later, in 1974, the University Council officially approved the crest as the school insignia of the University of Tsukuba. The “five-and-three paulownia” design is based on a traditional Japanese motif, but brings a unique variation to the classic style: the University of Tsukuba crest is different because only the outline of the leaves is depicted. The color of the crest is CLASSIC PURPLE, the official color of the University of Tsukuba. ■ Slogan (Japanese) 開かれた未来へ。 Since its inception, the University of Tsukuba’s philosophy has been one of openness as we seek to forge a better future through education, research, and all other aspects of academia. -

Ram, Andrew, Arthur, I've learned so much from each of you about such different things. Ram, I couldn't hope to find a more supportive mentor to help me develop into a mature scientist. Being a scientist is more than a career, it's a way of life. You have helped me develop scientific aesthetic, and have shown me how to conduct myself in research, and collaborative endeavours. Everything is interesting, but I will continually strive to focus on what is important. To the MeRL, which has been a warm and welcoming home, as well as a dynamic and exuberant research community to belong to. I have discovered what it means to be a part of a research community, and it has been my great pleasure and honor to work with such amazing people, at such an incredible institution. -

Microwave Assisted Synthesis of Thermoelectric Nanostructures
ROYAL INSTITUTE OF TECHNOLOGY Microwave assisted synthesis of thermoelectric nanostructures: p- and n-type Bi2-xSbxTe3 VIKING ROOSMARK Master of Science Thesis Department of Applied Physics KTH – Royal Institute of Technology Stockholm, Sweden 2018 1 (37) Supervisor Mr. Bejan Hamawandi [email protected] Examiner Prof. Muhammet S. Toprak [email protected] Biomedical and X-Ray Physics KTH/Albanova SE-106 91 Stockholm TRITA-SCI-GRU 2018:416 2 (37) Abstract Improving the way energy can be obtained, is becoming increasingly important from both environmental and economical aspects. Thermoelectric (TE) materials can be a stepping stone in the right direction for better energy management, seeing how they can recycle waste heat and generate electricity from energy that otherwise would be wasted. In recent years TE materials have been the focus of several projects to find materials which can easily and inexpensively be used in devices to harvest heat and produce clean energy, which is aimed by this project. TE nanomaterials based on the Bi2-xSbxTe3 system with different stoichiometry (x) have been synthesized using a bottom-up microwave (MW) assisted synthesis method. Nanopowders have been consolidated with SPS into pellets to examine their TE transport properties. The purpose of the project was to fabricate p- and n-type TE materials with comparable thermal expansion, for the purpose of obtaining a high efficiency TE device with high durability. The MW assisted synthesis shows highly reproducible results with nanopowders having good uniformity with low to none batch to batch variation in the powder composition. One of the most important aspects of this technique is the process speed, the MW heating itself only takes 2-3 min to synthesize the desired TE material using the developed thermolysis route. -

High-Yield Synthesis of Single-Crystalline Antimony Telluride Hexagonal Nanoplates Using a Solvothermal Approach Wenzhong Wang,* Bed Poudel, Jian Yang, D
Published on Web 09/17/2005 High-Yield Synthesis of Single-Crystalline Antimony Telluride Hexagonal Nanoplates Using a Solvothermal Approach Wenzhong Wang,* Bed Poudel, Jian Yang, D. Z. Wang, and Z. F. Ren* Department of Physics, Boston College, Chestnut Hill, Massachusetts 02467 Received July 20, 2005; E-mail: [email protected]; [email protected] There is a growing interest in nanostructured thermoelectric (TE) materials since both theoretical predictions1,2 and experimental results3,4 suggest that large improvements in figure-of-merit (ZT) could be achieved in nanostructured systems. If the ZT is improved to be ∼3, then TE coolers and power generators will become competitive with conventional compressor-based refrigerators and 5 power sources. Antimony telluride (Sb2Te3) belongs to layered semiconductors with tetradymite structure. This compound and its doped derivatives are considered to be the best candidates for near room-temperature TE applications.6 For instance, specially con- structed Bi2Te3/Sb2Te3 superlattices were reported to exhibit a ZT of ∼2.4 at room temperature.6 However, so far, there are only a few reports on the synthesis of polycrystalline Sb2Te3 nanowires using electrochemical deposition into the channels of the porous anodic alumina membrane.7It is therefore essential to develop an alternative approach to prepare a large quantity of nanosized single- crystalline Sb2Te3 materials to meet the demand of high- performance TE applications. Although various chemical methods have so far been developed to prepare nanostructured materials with different platelike shapes, these methods mainly focus on the fabrication of metal nanostruc- tured materials, such as Ag nanoplates,8,9 Ag nanodisks,10,11 Au 12 13-15 nanodisks, Au nanoplates. -
