Abstract

Here, our objective is to deploy a multiscale simulator for thermoelectric cooler devices, where the material parameters are obtained atomistically using a combination of molecular dynamics and tight-binding simulations and then used in the system level design. In a recently published work [A. Sharmin, M. Rashid, V. Gaddipati, A. Sadeque, and S. Ahmed, “Multiscale Design of Nanostructured Thermoelectric Coolers: Effects of Contact Resistances,” Journal of Electronic Materials, in press, DOI: 10.1007/s11664-014-3520-8, November 2014], after benchmarking the simulator against a recent experimental work [I. Chowdhury, R. Prasher, K. Lofgreen, G. Chrysler, S. Narasimhan, R. Mahajan, D. Koester, R. Alley and R. Venkatasubramanian, “On-chip cooling by superlattice-based thin-film thermoelectrics”, Nature Nanotechnology, vol. 4, pp. 235–238, 2009], we carried out a detailed numerical investigation of the performance of Bi2Te3 nanowire based thermoelectric devices for hot-spot cooling. The results suggest that active hotspot cooling of as much as 23 ºC with a high heat flux is achievable using such low-dimensionality structures. However, it has been observed that thermal and electrical contact resistances, which are quite large in nanostructures, play a critical role in determining the cooling range and lead to significant performance degradation that must be addressed before these devices can be deployed in such applications.
