We found that the Seebeck coefficient and power factor per area depend on the nanowire size and its orientation. In addition, for nano-scale nanowires, cross-sectional shape effect is considerable and transmission mode dominates the performance. Temperature also has a great impact on the thermoelectric performance of nanowires. The power factor of Si nanowires along different orientations is approaching to the same value as temperature growing higher than 300 K; while power factor of Ge nanowires along  is the largest at high temperature, but the smallest at extreme low temperature. ©2010 IEEE.||Source Title:||ICSICT-2010 - 2010 10th IEEE International Conference on Solid-State and Integrated Circuit Technology, Proceedings||URI:||http://scholarbank.nus.edu.sg/handle/10635/84297||ISBN:||9781424457984||DOI:||10.1109/ICSICT.2010.5667699|
