A p-n Sandwich Structure Peltier Device with a Sharp Microtip for Cooling/Heating Micro-objects
Year: 2008
Type: article
Abstract: A thermoelectric solid-state cooling/heating device applicable for small objects was proposed and fabricated as an alternative to the conventional π-shaped device. The device includes a sharp microtip that is positioned between p- and n-type -based bulks, and the tip can be easily exchanged when different targets are cooled or heated. The typical tip size is , and the smallest size is . The tip temperature reached during cooling at a current of 28 A (18.2 W) and during heating at a current of 20 A (12.2 W) when the hot side was set to . The smallest time constant of the device during cooling was as small as 1.0 s at a current of 32 A (23.1 W), and that during heating was 2.0 s at a current of 20 A.
