| Abstract | Solid state thermoelectric cooling devices have been of current interest for hot-spot thermal management. Cooling hot-spots with high heat flux is becoming one of the most important technical challenges facing today's IC industry. The rising temperature limits device minimization and decreases its lifetime. The thermoelectric effect is the appearance of an electric field along a temperature gradient established in a material. The inverse effect, called the Peltier effect, can be used for refrigeration, which uses electricity to pump heat from the cold end to the hot end. In this paper, we report to fabricate an in-plan solid-state thermoelectric cooling device using multilayered $Bi_{2}Te_{3}/Sb_{2}Te_{3}$ and $Bi_{2}Te_{3}/Bi_{2}Te_{3-x}Se_{x}$ thin films. A solid-state in-plan thin film cooling device has been fabricated using multilayered thermoelectric thin films. $Bi_{2}Te_{3}/Sb_{2}Te_{3}$ and $Bi_{2}Te_{3}/Bi_{2}Te_{3-x}Se_{x}$ multilayer thin films were deposited using e-beam evaporation. Solid antimony (III) telluride and bismuth (III) telluride were evaporated to grow the $Bi_{2}Te_{3}$ and $Sb_{2}Te_{3}$ layers for the $Bi_{2}Te_{3}/Sb_{2}Te_{3}$ multilayer films. Bi, Te, and Se powders were mixed with the ratio of 2:2.7:0.3 and were heated at 700degC under nitrogen and melted into solid $Bi_{2}Te_{3-x}Se_{x}.$ The thermally-grown solid $Bi_{2}Te_{3-x}Se_{x}$ was then evaporated to grow the $Bi_{2}Te_{3-x}Se_{x}$ layer for the $Bi_{2}Te_{3}/Bi_{2}Te_{3-x}Se_{x}$ multilayer thin film together with the $Bi_{2}Te_{3}$ layer using e-beam evaporation. The $Bi_{2}Te_{3}/Sb_{2}Te_{3}$ and $Bi_{2}Te_{3}/Bi_{2}Te_{3-x}Se_{x}$ multilayer thin films have a periodic structure consisting of alternating $Bi_{2}Te_{3}$ and $Sb_{2}Te_{3}$ layers or $Bi_{2}Te_{3}$ and $Bi_{2}Te_{3-x}Se_{x}$ layers, where each layer is about 10 nm thick. The films were analyzed by XRD, SEM, and AFM. The e-beam-grown $Bi_{2}Te_{3}/Sb_{2}Te_{3}$ multilayered thin film has a resistivity of $7.1times10^{-4}$ Omegaldrcm and an in-plan Seebeck coefficient of 110 muV/K, and the e-beam-grown $Bi_{2}Te_{3}/Bi_{2}Te_{3-x}Se_{x}$ multilayered thin film has a resistivity of $1.6times10^{-4}$ Omegaldrcm and an in-plan Seebeck coefficient of -95 muV/K. An in-plan cooling device was fabricated with the $Bi_{2}Te_{3}/Sb_{2}Te_{3}$ and $Bi_{2}Te_{3}/Bi_{2}Te_{3-x}Se_{x}$ films using the standard integrated circuit (IC) fabrication process; the cooling device is consisted of 2080 pairs of p-type and n-type elements, where each element is 200 mum long and 50 mum wide; pn junction diodes were fabricated as thermometers for the measurement of temperature difference between the two ends of device. Temperature difference was achieved between the hot and cold ends under an applied DC current. The developed in-plan cooling device can be a good candidate for the application of highly-efficient micro- cooling. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
